The supply curve is generally upward sloping, indicating a direct relationship between price and quantity supplied. As the price of a good increases, producers are willing to supply more, driven by the potential for higher profits. However, there can be exceptions, such as a perfectly elastic supply curve (horizontal), where producers supply any quantity at a fixed price, or a perfectly inelastic supply curve (vertical), where the quantity supplied is fixed regardless of price. In some cases, the supply curve can even be backward-bending, particularly for labor, where higher wages may lead to a decrease in the quantity supplied.
