Answer:

Step-by-step explanation:

y = mx + b

m is the slope (what you want)

b is the y-intercept, which is the value of y when x = 0

Oh, right, we already have b, isn't that great!

Given point (0, -4), so b = -4

Point (-2, -1), where x = -2 and y = -1

-1 = -2m -4 (solve for m)

3 = -2m

m = -3/2

Check:

y = -3x/2 -4

y = -3(-2)/2 -4  -> should get y = -1

y = 3 -4 = -1

Yay, we have the answer!
