Graphing the BC. Suppose that an individual has a weekly income of $180 to spend on goods X and Y, which have prices of $2 and $6, respectively. In the space below, using a straight edge and proper scaling, graph the budget constraint. Suppose that the price of X increases to 6. On the same graph, draw the new budget constraint. Compute the slopes of the old and new budget constraints and label them on the graph.
