| Question 136591:  This is a question from my Economics Course. No one in my group can figure it out. We are supposed to plot a Supply, Price, and Quantity graph based off the answer/s we get from the algebraic equation given. Here are the questions, exactly as they appear in the book:
 Assume that the demand and supply equations for bushels of wheat are a follows:
 Qd = 15 - (3*P)
 Qs =  1 + (4*P)
 Also assume that, in equilibrium, Qd = Qs. Solve for equilibrium price by setting quantity demanded equal to quantity supplied. What is the disequilibrium condition at prices of $1.50 and $2.50?
 
 I appreciate any help you can give us.
 Thank you!

      (Show Source): 
You can put this solution on YOUR website! the Quantity (in bushels) is plotted on the vertical (y) axis __ the Price (in dollars) is plotted in the horizontal (x) axis
 
 there are two lines, one for supply and another for demand
 __ they intersect at the equilibrium price point
 
 the equations are in slope-intercept form __ think of Q as y and P as x
 __ Q=mP+b
 __ Qd has a negative slope (downward from left to right)
 __ Qs has a positive slope (upward from left to right)
 
 the simultaneous solution for the equilibrium point
 __ 15-(3*P)=1+(4*P) __ 14=7P __ 2=P
