We draw a demand curve to show the relationship between the price of the good and the quantity that consumers are willing to buy. For example, suppose people are willing to buy 20 pounds of strawberries at a price of $2, but are willing to buy 30 pounds if the price falls to $1.
The demand schedule and demand curve are complementary ways of examining the relationship between price and quantity demanded. The demand schedule helps create the demand curve. The individual rows in the demand schedule, showing specific price points and quantity demanded, provide the coordinates to be plotted on the graph.
