Answer
y= 3/2 x - 2
Explanation:
so you have to find the slope which would be
m =
y2 - y1
x2 - x1
then you find you points that you are using (2, 1) and (0, -2)
when you plug it in it is
m=
-2-1
0-2
you simplify the numbers and get rid of the negatives to get m=3/2 x
then your y intercept is where your line meets the y axis or wherever x=0
so your y intercept is (0, -2) so the b = -2
