Answer:

y = (3/2)x + 7

Step-by-step explanation:

(−4, 1) and (−2, 4)

 

slope m = rise/run = (4-1)/(-2-(-4)) = 3/2

 

Slope intercept form is y=mx+b

where m=slope, b = y-inercept

 

y = (3/2)x + b

 

Use one of the given points for (x,y) to find b

 

1 = (3/2)(-4) + b

1 = -6 + b

7 = b

 

y = (3/2)x + 7
