atroni [7]

Answer:

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points (-5, 0) and (-1, -8). Substitute:

$m=\dfrac{-8-0}{-1-(-5)}=\dfrac{-8}{4}=-2$

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercpet

Put the value of the slope and coordinates of the point (-5, 0) to the equation of a line:

$0=-2(-5)+b$

$0=10+b$ <em>subtract 10 from both sides</em>

$-10=b\to b=-10$

Finally:

$y=-2x-10$
