Figure 4-7 A graph shows Quantity on the horizontal axis and Price of Wheat on the vertical axis. The horizontal axis notes the following values in increasing order: Q sub 1, Q sub 2, and Q sub 3. The vertical axis notes the following values in increasing order: P sub 1 and P sub F. An upward-sloping supply curve, S, and a downward-sloping demand curve, D, are plotted on the graph. The intersection of D and S has coordinates: ? (Q sub 2, P sub 1). ? a vertical dashed line is drawn from (Q sub 2, 0) to (Q sub 2, P sub 1) ? a horizontal dashed line is drawn from (0, P sub 1) to (Q sub 2, P sub 1). A point on the demand curve has coordinates: ? (Q sub 1, P sub F) ? A vertical dashed line is drawn from (Q sub 1, 0) to (Q sub 1, P sub F) ? A horizontal dashed line is drawn from (0, P sub F) to (Q sub 1, P sub F) A point on the supply curve has coordinates: ? (Q sub 3, P sub F) ? A vertical dashed line is drawn
