Answer:

y=1.5x+2

Step-by-step explanation:

Step 1, find slope

(20-8)/(12-4)

12/8 = 1.5

slope = 1.5

Step 2, find the y-intercept

y = 1.5x+b

use point (4,8)

8 = 1.5(4)+b

8 = 6+b

-6 -6

2 = b

Step 3, put it all in slope-intercept form (y = mx+b)

y = 1.5x+2

Answer: y = 1.5x+2
The answer to this question is y=1.5+2
