Question

The ordered pairs below represent a relation between x and y.

(-3,0), (-2,4), (-1,8), (0,12), (1,16), (2,20)

Could this set of ordered pairs have been generated by a linear function?

A. No, because the y-values decrease and then increase
B. No, because the distance between consecutive y-values is different than the distance between consecutive x-values
C. Yes, because the distance between consecutive x-values is constant
D. Yes, because the relative difference between y-values and x-values is the same no matter which pairs of (x, y) values you use to calculate it
