Answer:

y =
(4)/(3) x -
(14)/(3)

Explanation:

The slope is the change in y over the change in x


(2 - -2)/(5-2) =
(4)/(3) This is our slope. We will use this and one of the points to find the y-intercept.

m = 4/3

x = 5

y =2

y =mx + b

2 =
(4)/(3) (5) + b

2 =
(20)/(3) + b Subtract
(20)/(3) from both sides

2 -
(20)/(3) = b


(6)/(3) -
(20)/(3) = b

-
(14)/(3) This is our y -intercept
