At the price of $2.28 per bushel, the supply of barley is 7,500 million bushels and the demand is 7,900 million bushels. At a price of $2.37 per bushel, the supply is 7,900 million bushels and the demand is 7,800 million bushels.

1. Find the price-supply equation of the p= mx+b.


2. Find the price demand equation of the form p= mx +b.


3. Find the equilibrium point.


4. Graph the price-supply equation, the price-demand equation, and the equilibrium point in the same coordinate system.
