What does the law of downward slope of demand indicate?

The law of downward slope of demand indicates that, all else being equal, as the price of a good or service decreases, the quantity demanded by consumers increases. Conversely, as the price increases, the quantity demanded typically decreases. This inverse relationship reflects consumers' tendency to buy more of a product when it is less expensive and less when it is more costly. The downward slope of the demand curve visually represents this principle in economic graphs.
