How is the law of supply typically represented on a graph?

The law of supply states that, all else being equal, an increase in the price of a good or service results in an increase in the quantity supplied. This relationship between price and quantity supplied is typically represented on a graph as an upward-sloping line from left to right.

This upward slope illustrates that suppliers are willing to offer more of the product at higher prices, reflecting their motivation to maximize profit. As the price increases, the potential revenue from selling the product becomes greater, encouraging suppliers to increase production to meet this demand. The steeper or gentler slope can indicate different levels of sensitivity (elasticity) of quantity supplied to price changes, but the fundamental representation remains an upward slope.

This graphical portrayal of the law of supply helps economists and students visualize how market dynamics work, especially in relation to price changes and supplier behavior.
