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 x-value 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. no, because the y-values decrease and then increase d. yes, because the distance between consecutive x-values is constant.
