Writing Equations of Lines Given the Graph
Write the slope-intercept form of the equation of each line.
questions are on the image below :)
Answer:
1. [tex]y = 3x[/tex]
2. [tex]y = -\frac{2}{3}x + 1[/tex]
3. [tex]y = -\frac{2}{3}x - 4[/tex]
4. [tex]y = 4[/tex]
5. [tex]y = x + 5[/tex]
6. [tex]y= \frac{5}{2}x[/tex]
7. [tex]y = -7x -16[/tex]
8. [tex]y = x + 4[/tex]
Step-by-step explanation:
The steps to solving these questions involve
1. Calculate slope using: [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
2. Calculate the line equation using point slope formula: [tex]y - y_1 = m(x - x_1)[/tex]
We'll apply the steps above in solving 1 through 8
Solving (1):
When x = 0; y = 0
When x = 1; y = 3
i.e.
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (1,3)[/tex]
Calculate slope:
[tex]m=\frac{3 - 0}{1 - 0}[/tex]
[tex]m=\frac{3 }{1 }[/tex]
[tex]m = 3[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (0,0)[/tex] and [tex]m = 3[/tex]
[tex]y - 0 = 3(x - 0)[/tex]
[tex]y = 3x[/tex]
Solving (2):
When x = 0; y = 1
When x = 3; y = -1
i.e.
[tex](x_1,y_1) = (0,1)[/tex]
[tex](x_2,y_2) = (3,-1)[/tex]
Calculate slope:
[tex]m=\frac{-1 - 1}{3 - 0}[/tex]
[tex]m= -\frac{2}{3}[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (0,1)[/tex] and [tex]m= -\frac{2}{3}[/tex]
[tex]y - 1 = -\frac{2}{3}(x - 0)[/tex]
[tex]y - 1 = -\frac{2}{3}(x)[/tex]
[tex]y - 1 = -\frac{2}{3}x[/tex]
[tex]y = -\frac{2}{3}x + 1[/tex]
Solving (3):
When x = 0; y = -4
When x = -3; y = -2
i.e.
[tex](x_1,y_1) = (0,-4)[/tex]
[tex](x_2,y_2) = (-3,-2)[/tex]
Calculate slope:
[tex]m=\frac{-2 - (-4)}{-3 - 0}[/tex]
[tex]m=\frac{-2 +4}{-3 - 0}[/tex]
[tex]m=\frac{2}{-3}[/tex]
[tex]m=-\frac{2}{3}[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (0,-4)[/tex] and [tex]m= -\frac{2}{3}[/tex]
[tex]y - (-4) = -\frac{2}{3}(x - 0)[/tex]
[tex]y +4 = -\frac{2}{3}(x)[/tex]
[tex]y +4 = -\frac{2}{3}x[/tex]
[tex]y = -\frac{2}{3}x - 4[/tex]
Solving (4):
When x = 0; y = 4
When x = 4; y = 4
i.e.
[tex](x_1,y_1) = (0,4)[/tex]
[tex](x_2,y_2) = (4,4)[/tex]
Calculate slope:
[tex]m=\frac{4 - 4}{4 - 0}[/tex]
[tex]m=\frac{0}{4}[/tex]
[tex]m = 0[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (0,4)[/tex] and [tex]m = 0[/tex]
[tex]y - 4 = 0(x - 0)[/tex]
[tex]y - 4 = 0[/tex]
[tex]y = 4[/tex]
Solving (5):
When x = -4; y = 1
When x = -1; y = 4
i.e.
[tex](x_1,y_1) = (-4,1)[/tex]
[tex](x_2,y_2) = (-1,4)[/tex]
Calculate slope:
[tex]m=\frac{4 - 1}{-1 - (-4)}[/tex]
[tex]m=\frac{4 - 1}{-1 +4)}[/tex]
[tex]m=\frac{3}{3)}[/tex]
[tex]m = 1[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (-4,1)[/tex] and [tex]m = 1[/tex]
[tex]y - 1 = 1(x - (-4))[/tex]
[tex]y - 1 = 1(x +4)[/tex]
[tex]y - 1 = x +4[/tex]
[tex]y = x +4 + 1[/tex]
[tex]y = x + 5[/tex]
Solving (6):
When x = 0; y = 0
When x = 2; y = 5
i.e.
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (2,5)[/tex]
Calculate slope:
[tex]m=\frac{5 - 0}{2 - 0}[/tex]
[tex]m=\frac{5 }{2 }[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (0,0)[/tex] and [tex]m=\frac{5 }{2 }[/tex]
[tex]y - 0 = \frac{5}{2}(x - 0)[/tex]
[tex]y - 0 = \frac{5}{2}(x)[/tex]
[tex]y= \frac{5}{2}x[/tex]
Solving (7):
When x = -2; y = -2
When x = 2; y = 5
i.e.
[tex](x_1,y_1) = (-2,-2)[/tex]
[tex](x_2,y_2) = (-3,-5)[/tex]
Calculate slope:
[tex]m=\frac{5 - (-2)}{-3 - (-2)}[/tex]
[tex]m=\frac{5 +2}{-3 +2}[/tex]
[tex]m=\frac{7}{-1}[/tex]
[tex]m =-7[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (-2,-2)[/tex] and [tex]m =-7[/tex]
[tex]y - (-2) = -7(x - (-2))[/tex]
[tex]y +2 = -7(x +2)[/tex]
[tex]y +2 = -7x -14[/tex]
[tex]y = -7x -14 - 2[/tex]
[tex]y = -7x -16[/tex]
Solving (8):
When x = -3; y = 1
When x = 0; y = 4
i.e.
[tex](x_1,y_1) = (-3,1)[/tex]
[tex](x_2,y_2) = (0,4)[/tex]
Calculate slope:
[tex]m = \frac{4 - 1}{0 - (-3)}[/tex]
[tex]m = \frac{4 - 1}{0 +3}[/tex]
[tex]m = \frac{3}{3}[/tex]
[tex]m = 1[/tex]
Next, we calculate the equation
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (-3,1)[/tex] and [tex]m = 1[/tex]
[tex]y - 1 = 1(x - (-3))[/tex]
[tex]y - 1 = 1(x +3)[/tex]
[tex]y - 1 = x +3[/tex]
[tex]y = x + 3 + 1[/tex]
[tex]y = x + 4[/tex]

Step-by-step explanation:
Properties of Logarithms
We'll recall below the basic properties of logarithms:
[tex]log_b(1) = 0[/tex]
Logarithm of the base:
[tex]log_b(b) = 1[/tex]
Product rule:
[tex]log_b(xy) = log_b(x) + log_b(y)[/tex]
Division rule:
[tex]\displaystyle log_b(\frac{x}{y}) = log_b(x) - log_b(y)[/tex]
Power rule:
[tex]log_b(x^n) = n\cdot log_b(x)[/tex]
Change of base:
[tex]\displaystyle log_b(x) = \frac{ log_a(x)}{log_a(b)}[/tex]
Simplifying logarithms often requires the application of one or more of the above properties.
Simplify
[tex]\displaystyle log_\frac{1}{2}(64)[/tex]
Factoring [tex]64=2^6[/tex].
[tex]\displaystyle log_\frac{1}{2}(64)=\displaystyle log_\frac{1}{2}(2^6)[/tex]
Applying the power rule:
[tex]\displaystyle log_\frac{1}{2}(64)=6\cdot log_\frac{1}{2}(2)[/tex]
Since
[tex]\displaystyle 2=(1/2)^{-1}[/tex]
[tex]\displaystyle log_\frac{1}{2}(64)=6\cdot log_\frac{1}{2}((1/2)^{-1})[/tex]
Applying the power rule:
[tex]\displaystyle log_\frac{1}{2}(64)=-6\cdot log_\frac{1}{2}(\frac{1}{2})[/tex]
Applying the logarithm of the base:
[tex]\mathbf{\displaystyle log_\frac{1}{2}(64)=-6}[/tex]
Find the difference

Step-by-step explanation:
Which point(s) are solutions to the inequality -x - 2y > 3? Select all that apply.
A. (-1, -2)
B. (1, -2)
C. (-2, -1)
D. (2.-4)
(-1, -2), (-2, -1) and (2, -4) are solutions to the inequality
The given inequality is:
-x - 2y > 3
To know which of the points given as options are the solutions to the given inequality, substitute the given points into -x - 2y, anyone that gives a result greater than 3 is a solution to the inequality
For (-1, -2)
Substitute x = -1, and y = -2 into -x - 2y
-(-1) - 2(-2)
= 1 + 4
= 5
Since 5 > 3, (-1, -2) is a solution to the inequality
For (1, -2)
Substitute x = 1, and y = -2 into -x - 2y
-(1) - 2(-2)
= -1 + 4
= 3
Since the result is not greater than 3, (1, -2) is not a solution to the inequality
For (-2, -1)
Substitute x = -2, and y = -1 into -x - 2y
-(-2) - 2(-1)
= 2 + 2
= 4
Since 4 > 3, (-2, -1) is a solution to the inequality
For (2, -4)
Substitute x = 2, and y = -4 into -x - 2y
-(2) - 2(-4)
= -2 + 8
= 6
Since 6 > 3, (2, -4) is a solution to the inequality
Therefore, (-1, -2), (-2, -1), and (2, -4) are solutions to the inequality

Find the appropriate side length of a square game board with an area of 175 inch squared
Answer:
13.29 inch
Step-by-step explanation:
Given:
Square game board.
Area of square game board = 175 sq inch
To find:
The side length of the square board game.
Solution:
First of all, we need to know the formula for area of a square.
Let us have a look at the formula for area of a square.
[tex]Area = Side\times Side[/tex]
OR
[tex]Area = Side^2[/tex]
Putting value of area = 175 sq in and let us find the value of Side.
[tex]175=Side^2\\\Rightarrow Side = \sqrt{175}\\\Rightarrow Side \approx \bold{13.29\ inch}[/tex]
Therefore, the answer is:
The appropriate side length of the square game board = 13.29 inch

A solid object with an initial temperature of 75 degrees Fahrenheit is dropped into a lake with a temperature of 33 degrees Fahrenheit. The function f(t)=Ce(−kt)+33 represents the situation, where t is time in minutes, C is a constant, and k is a constant.
After 2 minutes the object has a temperature of 55 degrees. What will be the temperature of the object, in degrees Fahrenheit, after 4 minutes? Round your answer to the nearest tenth, and do not include units.
Answer: 44.5
Step-by-step explanation:
The object's temperature post 4 minutes in respect to degrees Fahrenheit would be:
- [tex]44.5[/tex]°C
Given that,
Function [tex]f(t)=Ce(-kt)+33[/tex]
where,
t = time in terms of minutes
C = constant
k = constant
The temperature of the object [tex]= 75[/tex]°
where, [tex]t = 0[/tex]
Using the function,
∵ [tex]f (0) = 75[/tex]
[tex]Ce^{(0)}[/tex] [tex]+ 33 = 75[/tex]
This will lead to
[tex]C = 42[/tex] (∵ C being constant)
Temperature post 2 minutes = [tex]55[/tex]°
or
[tex]55 =[/tex] [tex]42e^{(-2k)} + 33[/tex] (k being [tex]0.3233[/tex])
Thus,
Temperature after 4 minutes would be:
[tex]f(4) = 42e^{(-1.29325)} + 33[/tex]
[tex]= 44.5[/tex]°
Thus, [tex]44.5[/tex]°C is the correct answer.

Step-by-step explanation:
Units of Length
The most common units of distance are millimeters, centimeters, meters, miles, and kilometers.
The equivalence from miles to kilometers is:
1 mile = 1.6 Kilometers
If we wanted to convert a given distance from kilometers to miles, we'd need to divide by 1.6, that is:
d(miles) = d(km)/1.6
The above equation can be used to find the number of miles given the number of kilometers.
If a car travels at 120 kilometers per hour, then in one hour it travels
d(km)=120
Thus, the distance in miles is:
d(miles) = 120/1.6 = 75
The car travels 75 miles per hour
