Graphs illustrating how changes in supply affect equilibrium price and quantity in a market.
Two supply and demand graphs showing the effects of supply changes: the top graph illustrates an increase in supply shifting the supply curve right, lowering price from P1 to P2 and increasing quantity from Q1 to Q2; the bottom graph shows a decrease in supply shifting the supply curve left, raising price from P1 to P2 and decreasing quantity from Q1 to Q2.
