Which equation represents line E, shown in the accompanying diagram?
A.)y=2x+3
B.)y=1/2x+3
C.)y=3x+1/2
D.)y=3x+2
Please help!!!!
Answer:
First, find the slope:
The slope is 1/2.
Now we have this much of the equation:
y = 1/2x + b
Plug in the point (0,3) to find the value of b
3 = (1/2)(0) + b
b = 3
Your final equation is y = 1/2x + 3.
Step-by-step explanation:
The equation of the line is y = x/2 + 3 which is passing through the points (-4, 1) and (0, 3) option (B) is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The straight line is shown in the coordinate plane.
The equation of the line passing through the points:
(-4, 1) and (0, 3)
From the two-point we can find the equation of the line:
y - 3 = (3-1)/(0+4)[x]
y = 2/4[x] + 3
y = x/2 + 3
Thus, the equation of the line is y = x/2 + 3 which is passing through the points (-4, 1) and (0, 3) option (B) is correct.

Answer:
X = 25
Step-by-step explanation:
As, 2x + 60° + 4x = 180° (bc they r supplementry)
So, 6x + 30° = 180°
6x = 180° - 30°
6x = 150°
x = 150/6
x = 25
Therefore, answer = 25

Anthony is going to invest in an account paying an interest rate of 2.7% compounded quarterly. How much would Anthony need to invest, to the nearest hundred dollars, for the value of the account to reach $130 in 10 years?
Answer:
$99
Step-by-step explanation:
Given that :
Rate (r) = 2.7% = 0.027 Compounded quarterly
Final amount (A) = $130
Period (t) = 10 years
Principal = invested amount (p) =?
n = number of compounding tines per period = 12/3 = 4
Using the formula :
A = p(1 + r/n)^nt
130 = p(1 + 0.027/4)^(4*10)
130 = p(1 + 0.00675)^40
130 = p(1.00675)^40
130 = p(1.3087766)
P = 130 / 1.3087766
P = 99.329402
P = $99

PLEASE HURRY 45 POINTS!!! which function is best represented by the graph A. g(x)=(1/3) B. g(x)=6(3) C. g(x)=6-(1/3) D. g(x)=6-(3)
Answer:
it is d. i had that question and i got it right
Step-by-step explanation:
The given line in the graph is represented by the equation g(x) = 6 - (3). The correct option is D.
A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
In the given graph the straight line is represented by the function g(x) = 6 - ( 3 ). The graph of the line is matched with the answer below.

Answer:
y = - 2 + [tex]\frac{1}{3}[/tex] x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (6, 0) ← 2 points on the line
m = [tex]\frac{0+2}{6-0}[/tex] = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]
The line crosses the y- axis at (0, - 2 ) ⇒ c = - 2
y = [tex]\frac{1}{3}[/tex] x - 2 , or
y = - 2 + [tex]\frac{1}{3}[/tex] x
Answer:
Proof
Step-by-step explanation:
"The y-intercept is - 2" and now I think the best way to prove the gradient is to prove it mathematically taking coordinates of the line and using:
[tex]m = \frac{y - y}{x - x} [/tex]
So I'll take the coordinates (6,0) and (0,-2) and substitute them in the formula for the gradient.
[tex]m = \frac{ - 2 - 0}{0 - 6} = \frac{ - 2}{ - 6} = \frac{1}{3} [/tex]
