Use the following graph showing the long-run supply and demand curves in a perfectly competitive industry to answer the next question. A graph depicts variation of Price on the vertical axis and Quantity on the horizontal axis.The horizontal axis lists labels from left to right as Q2, Q0, and Q1. The vertical axis lists labels from bottom to top as P1, P0, and P2. A straight line labeled supply, from P0 at the vertical axis intersects a decreasing line labeled, demand at data point (Q0, P0). Dotted straight lines from P1 and P2 at the vertical axis and Q2, Q0, and Q1 at the horizontal axis connects to the demand curve. The curves suggest that this is Multiple Choice a decreasing-cost industry. a constant-cost industry. an increasing-cost industry. not possible, because the supply curve is always upward sloping
