By the way this looks, this is a linear relationship. By marking points on a graph, I can see that Ahmad payed 30 dollars more total, and if he payed 4 dollars per movie, and 5 dollars per game, then it adds up for the first part but not the second. We would have to have decimal points, but graphing does not work for this. It's a start
B, the first differences are not the same , that proves it is not linear. The second set of differences are the same this shows it is a quadratic function.
