What is true regarding the supply curve in economics?

The supply curve indeed indicates sellers' behavior, reflecting how much of a good or service suppliers are willing to sell at various price levels. It represents the relationship between price and quantity supplied, illustrating that as prices increase, suppliers are generally willing to offer more of the good to the market. This is due to the potential for higher revenues and profits at higher prices, which incentivizes producers to increase their output.

The upward slope of the supply curve is a fundamental concept in economics, signifying that higher prices lead to greater quantities supplied, a response driven primarily by producers' profit motives rather than consumer preferences or demand dynamics. Understanding this aspect is crucial for analyzing market behaviors, pricing strategies, and overall economic equilibrium.
