C.
Yes, because all the ratios of y to x are equal to -2.
D.
Yes, because all the ratios of y to x are equal to -4.

Answer 1

I'd say it is a proportional relationship (linear equation) because it has a linear rate of growth. An exponential relationship grows similar to this
2 4 8 16 32 64 128 etc
