Answer: y= 3x + 8

Explanation:

First find the slope of the line between (0,8) and (-2,2) using m= y2-y1/x2-x1, which is the change of y over the change of x.

It would be 2-(8)/-2-(0)

Next multiply 1 . 8, then subtract 8 from 2.

= 2-8/ -2 -(0)

= -6/-2-(0)

Next, multiply -1 . 0

= -6/-2+0

Add -2 and 0

= -6/-2

Divide -6 by -2

m= 3

Next, use the slope 3 and our last given point (0,8) to substitute for x1 and y1 in the point-slope form y-y1 = m(x-x1).

y-(8) = 3. (x-(0))

Next, simplify the equation and keep it in point-slope form

y-8 = 3. (x+0)

Then solve for y

add x and 0

y-8= 3x

add 8 to both sides of the equation

y= 3x + 8
