A demand curve illustrates the law of demand which states that when everything else is held constant as price?

A demand curve illustrates the law of demand by showing the inverse relationship between price and quantity demanded. When the price of a good decreases, consumers tend to buy more of it, leading to a movement along the demand curve to a higher quantity. Conversely, as the price increases, the quantity demanded typically decreases. This relationship holds true when all other factors affecting demand remain constant.
