Answer:
y =
Step-by-step explanation:
Each point is (x,y). So to find the equation, substitute both points into the given choices.
To test the first choice: y = substitute -8 into x and -6 into y
-6 =
-6(3) = (-4)(-8)
-18 ≠ 32
Since the numbers are not equal this is not the correct equation. Move on to testing the next equation in the same manner.
The third equation y = satisfies both points
Test for point (-8,-6)
-6 =
-6(4) = (3)(-8)
-24 = -24
Test for point (12,9)
9 =
9(4) = (3)(12)
36 = 36
