Answer:
3rd group of possible answers is the correct set
Step-by-step explanation:
Each of the three points in the 3rd line of possible answers is a solution of the given equation, as can be verified by substitution:
If x = -2, y = -8(-2) = +16
If x = 3, y = -8(3) = -24
If x = -4, y = -8(-4) = +32
Answer- seriously? Not sure if I should answer this. But it’s 4 (duh)
Step-by-step explanation:
You already know. You have two, add two, 4.
