Answer:

Sorry for late response, but I believe it may be 2x - y - 3 = 0.

Step-by-step explanation:

The general form of the equation of the line shown is,

⇒ y = - x + 3

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (2, 1) and (0, 3).

Now,

Since, The equation of line passes through the points (2, 1) and (0, 3).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (3 - 1)) / (0 - 2)

m = 2 / - 2

m = - 1

Thus, The equation of line with slope - 1  is,

⇒ y - 1 = - 1 (x - 2)

⇒ y - 1 = - x + 2

⇒ y = - x + 2 + 1

⇒ y = - x + 3

Therefore, The general form of the equation of the line shown is,

⇒ y = - x + 3

Answer:

A. 3/10

Step-by-step explanation:

0.25 = 2.5/10

2.5/10 < 3/10

Answer:

It is 3/10 because it doesn't need approximation to give 0.3

Answer:

(0,-5)

Step-by-step explanation:

First you want to simplify this equation by distributing the 3 into x-4:

y+9 = -3x+4

Next subtract 9 from both sides:

y= -3x -5

Now since I am assuming you want the Y-Intercept because you didn't ask for a specific point then it passes through the Y axis at the point (0,-5)

Answer:

i chose two points on the line and i got 5/1 (by using the rise over run method) which is simplified to 5 so the slope is going to be m= 5

Answer:  1/3

Step-by-step explanation: From what I can see, when y is 1, x is 3. slope is y2-y1/x2-x1

The pairs are (0,0) and (3,1). 1-0 is 1 and 3-0 is 3. Therefore the slope is 1/3

Answer:

y = 3x + 3

Step-by-step explanation:

Step-by-step explanation.

A system of equations is basically two or more equations that rely on each other. If a solution for a variable is 2, it has to work for the other equation.

The substitution is basically plugging in the y value to y = 8x + 10

If y = 2

and also y = 8x + 10

What do you think the substitution is?

Answer:

Step-by-step explanation:

The slope-intercept form is the only way to solve this problem.

Slope-intercept form:

[tex]\rightarrow \sf{y=mx+b}[/tex]

Using the slope is another way to solve.

Use a slope formula.

Slope:

[tex]\sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{rise}{run} }[/tex]

y2= (-9)

y1= (-9)

x2= (-3)

x1= (1)

Rewrite the problem.

[tex]\sf{\dfrac{(-9)-(-9)}{(-3)-1}=\dfrac{0}{-4}=\boxed{\sf{0} }[/tex]

We're not done yet.

y-intercept= (-9).

The m represents is 0.

The b represents is (-9).

I hope this helps you! Let me know if my answer is wrong or not.

Answer:  I have provided a screenshot of what your graph should look like so uh yeah you got this!

The graph of the line with the equation y = 4/5x + 2 is given in below attachment.

To graph the line with the equation y = (4/5)x + 2, we can use the slope-intercept form, which is y = mx + b.

where "m" represents the slope and "b" represents the y-intercept.

In this case, the slope (m) is 4/5, and the y-intercept (b) is 2.

To plot the line, we can start by plotting the y-intercept, which is the point (0, 2).

From there, we can use the slope to find additional points and connect them to form the line.

Let's plot a few more points:

When x = 5:

y = (4/5)(5) + 2

= 4 + 2 = 6

So we have the point (5, 6).

When x = -5:

y = (4/5)(-5) + 2

= -4 + 2

= -2

So we have the point (-5, -2).

Step-by-step explanation:

Side QP is equal to side QR so 4x-2=10, then just solve for x and you get 3

Answer:

x=3

Step-by-step explanation:

the trangal is isosoles so both sides need to equal 10 so the equation would be 4x-2=10.

frist you would add both sides by 2

4x-2=10

    +2 +2

4x=12

then you would divide both sides by 4

4x/4=12/4

Step-by-step explanation:

        Scientific scientific notation  is where the super small / super large number is multiplied by a 10 (E) to the power of a number. Here, the number is smaller than 8.5 so our power must be negative. As we are making it four "places" bigger, we use the exponent of -4.

Answer:

First, let’s use what we know to determine how many miles Rosa can run in a minute.

We do so by dividing 4 by 56 (4/56), which equals .071, after rounding.

So, Rosa runs .071 miles in a minute. Now we multiply this by 42 to get our final answer.

42 x .071 = 2.98. Using rounding, we know that Rosa can run 3 miles in 42 minutes.

If x represents Lily's age and y represents Kenny's age. The equation representing the given condition is x-2y=6.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

Given that, there are 6 years between Lily and Kenny, who are twice her age. Kenny is younger than Lily. Let x and y stand in for Lily's and Kenny's ages, respectively.

Let x represent Lily's age and y represent Kenny's age.

If the difference between Lily's age and twice Kenny's age is 6 years.

x-2y=6

If Lily is older than Kenny.

x>y

Thus, if x represents Lily's age and y represent Kenny's age. The equation representing the given condition is x-2y=6.
