The long-run supply curve indicates the price and the general production of a particular economy (real GDP). The curve indicates the long-run changes in prices and their relation to change in the supply quantity at that given period. A price change may change the quantity supplied according to the law of supply. When prices increase, supply quantity also increases, and vice versa.
