Figure 6-4 A graph of price, P, versus quantity, Q, shows a supply curve, S, rising linearly from the origin with a slope of one, and a demand curve, D, descending linearly from (0, 20) to (20, 0). The curves intersect at (10, 10). The following points are shown on the supply curve. (6, 6), (10, 10), (16, 16). The following points are shown on the demand curve. (4, 16), (8, 12), (10, 10), (14, 6). Refer to Figure 6-4.
