Figure3-1The Demand Schedule and the Demand Curve The demand schedule for cotton yields the corresponding demand curve, which shows how much of a good or service consumers want to buy at any given price. The demand curve and the demand schedule reflect the law of demand: all other things equal, as price rises, the quantity demanded falls. Similarly, all other things equal, a fall in price raises the quantity demanded. As a result, the demand curve is downward sloping.
