A normal supply curve has a positive slope which indicates that sellers are willing to sell more at a higher price. This means that as the price of a good or service increases, sellers are willing to supply more of that good or service to the market. Conversely, as the price of a good or service decreases, sellers are willing to supply less of that good or service to the market. The positive slope of the supply curve reflects the basic principle of supply and demand, where the price of a good or service serves as a signal to producers about the level of demand in the market, and producers respond by adjusting their output accordingly.
