Consider the equations for the following straight-line supply curves. In each case, p is the price (measured in dollars per unit) and QS is the quantity supplied of the product (measured in thousands of units per month). Supply A: pQSA, and Supply B: pQSB a. Plot each supply curve on a scale diagram. In each case, plot point 1, which corresponds to price equal to $20, and point 2, which corresponds to price equal to $40. 1.) For each supply...
