Graphing Changes in Supply and Demand


Students shall be able to

  1. identify market equilibrium,

  2. identify market equilibrium graphically,

  3. define equilibrium price,

  4. define equilibrium quantity,

  5. name the two forces that are equal at equilibrium,

  6. explain why the equilibrium price is special,

  7. define surplus,

  8. define shortage,

  9. identify surplus graphically,

  10. identify shortage graphically,

  11. identify the effect of changes in supply and demand on equilibrium price and quantity, and

  12. define indeterminate.



  1. Students shall complete an exercise about shifting supply and demand, and the effect on price and quantity.


Assignment: Complete the cotton graphing exercise. [Click here for blank graphs on which to draw the results in that exercise.]



Monitor and adjust, as needed. Check the graphs when notebooks are collected.
