6. The Law of Supply The law of supply states that: producers will increase the quantity supplied at higher prices and decrease the quantity supplied at lower prices, if everything else remains the same. When graphing supply and demand, this is known as a change in quantity supplied.

7. What are the determinants of supply? Essential Question:

8. Determinants of supply can change supply. A change in supply results from : • changes in the prices of productive resources used to make the good or the service • changes in the technology used to make the good or the service • changes in the profit opportunities available to producers by selling other goods or services • changes in the number of sellers in a market • changes in the expectations of producers. When graphing, this is known as a change in supply The Determinants of Supply
