The price P of a product is determined by a balance between production at each price (supply S) and the desires of those with purchasing power at each price (demand D). The graph depicts an increase in demand from D1 to D2, along with a consequent increase in price and quantity Q sold of the product.

The intersection of supply and demand curves determines equilibrium price (P0) and quantity (Q0).

An out-ward or right-ward shift in demand increases both equilibrium price and quantity

An out-ward or right-ward shift in supply reduces equilibrium price but increases quantity
