The ordered pairs below represent a relation between x and y. (-3,1), (-2,3), (-1,5), (0,7), (1,9), (2,11). could this set of ordered pairs have been generated by a linear function? . a) yes, because the distance between consecutive x-values is constant. b) no, because the distance between consecutive y-values is different than the distance between consecutive x-values. c) 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. d) no, because the y-values decrease and then increas
