Draw three graphs, one directly above the other. On the first graph, label the vertical axis Good X and label the horizontal axis Good Y. On the second graph, label the vertical axis the Price of good Y and label the horizontal axis Good Y. On the third graph label the vertical axis the income and label the horizontal axis Good Y. In the first graph, show the income and substitution effects of increase in the Price of good Y when Y is a Normal good as well as increases in income level. Draw the corresponding demand curve for Good Y in the Second graph and Draw Engle curve for Good Y in the third graph
