What is the salient features of the demand curve?

The demand curve typically slopes downward from left to right, indicating that as the price of a good decreases, the quantity demanded increases, and vice versa. This relationship reflects the law of demand, which suggests that consumers are more willing to purchase a product at lower prices. The demand curve can also shift due to factors such as changes in consumer preferences, income levels, and the prices of related goods. Additionally, the curve may exhibit elasticity, showing how responsive quantity demanded is to price changes.
