Solve the problem.Let the supply and demand equations for a certain model of electric pencil sharpener be given by p = 
q and p = 18 - 
q ,where p is the price in dollars and q is the quantity of pencil sharpeners (in hundreds). Graph these equations on the same axes (graph the supply equation as a dashed line and the demand equation as a solid line). Also, find the equilibrium quantity and the equilibrium price.
