2. Plot the input combinations in the table on a graph that contains clerks on the vertical axis and machines on the horizontal axis. Connect the points by lines to approximate an isoquant as pictured in Figure 5.6. Add the cost minimizing isocost curve to the graph (you can derive this line from the input prices and the total cost of the low-cost input combination).

How do the slopes of the isocost curve and isoquant compare at the optimal input combination?
