B. The relationship is linear; y-5=2(x+7)

C. The relationship is not linear.

D. The relationship is linear; y+7=1/2(x-5)

Answer 1

Hello Macie.

If the relation is linear then there is constant difference between x values; also there is constant difference between y values

x increase by 2;

y increase by 4;..... then it is linear

you can find slope by difference of y/difference of x = 4/2= 2;

Please look at the answer choices which one gives slope = 2? that is the right answer

hope that helps
