supply curve:

It is a graph (and more technically, a locus of points) that shows the relationship between quantity supplied of a commodity and the market price when all other supply factors are held constant.  The normal supply curve has a positive slope or slopes upward from left to right showing that more is willingly supplied by firms at higher prices than lower prices. The supply curve is the graphical representation of the information in the supply schedule ( i.e. plotting prices against corresponding quantities supplied).   The supply curve, SS, in Figure 2.6 is drawn from the supply schedule of Amala om Table
