Why does a normal supply curve always increase from left to right on a supply graph?

A normal supply curve increases from left to right due to the law of supply, which states that as the price of a good or service rises, producers are willing to supply more of it. This is because higher prices typically incentivize suppliers to allocate more resources and production towards that good, anticipating greater profits. Additionally, as production increases, suppliers may encounter higher costs, which further justifies the need for a higher price to maintain profitability.
