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 distance between consecutive y-values is different than the distance between consecutive x-values 

B 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. 

C yes, because the distance between consecutive x-values is constant 

D no, because the y-values decrease and then increase.
