What is the Law of Supply?

All other things being equal, if the price of a good increases, the supply of that good will increase, and this is known as the Law of Supply. The Supply Curve is plotted on a graph with a y-axis being price and an x-axis being quantity.

The relationship is positive and the line will climb up to the right. The is the opposite direction of the Demand Curve, and the place where the two intersect is considered to be the point of market equilibrium. The curves can be shifted by variables not present on the graph, such as changes in levels of income and other factors, but the slopes will remain the same, theoretically.
