Answer:
The equation of the line in slope-intercept form is: <em>y</em> = -2x - 10
Step-by-step explanation:
An equation for a line that passes through the points <em>A</em> = (−5, 0) and <em>B</em> = (−1, −8).
The formula to compute the slope, using two point is:
![\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=%5Ctext%7BSlope%7D%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
Compute the slope of the line as follows:
![\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=%5Ctext%7BSlope%7D%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
![m=\frac{-8-0}{-1+5}\\\\](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-8-0%7D%7B-1%2B5%7D%5C%5C%5C%5C)
![=\frac{-8}{4}\\\\=-2](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-8%7D%7B4%7D%5C%5C%5C%5C%3D-2)
The slope of the line is -2.
Compute the equation of the line as follows:
![(y-y_{1})=m\times (x-x_{1})](https://tex.z-dn.net/?f=%28y-y_%7B1%7D%29%3Dm%5Ctimes%20%28x-x_%7B1%7D%29)
![y-0=-2\times (x+5)](https://tex.z-dn.net/?f=y-0%3D-2%5Ctimes%20%28x%2B5%29)
![y=-2x-10](https://tex.z-dn.net/?f=y%3D-2x-10)
The <em>y</em>-intercept of the line is -10.
The equation of the line in slope-intercept form is:
<em>y</em> = -2x - 10

Answer:
(5,10)
Step-by-step explanation:
(-10x + 7y = 20)8 -80x + 56y = 160
(8x - 6y = -20)10 + 80x - 60y = -200
-4y = -40
y = 10
Plug 1 in for y into the first equation
-10x + 7(10) = 20
-10x + 70 = 20
- 70 - 70
-10x = -50
x = 5
