    2. Using the equation of a line, what is the algebraic formula of this demand curve?

     

    Hint

    3. Suppose the equation of the line changes to P = -5*Q + 75. Compute the quantity demanded at each indicated price.

    Price: $50, Quantity:

    Price: $40, Quantity:

    Price: $30, Quantity:

    Price: $20, Quantity:

    Price: $10, Quantity:

    Hint



    4. Let's call the original demand curve (from Question 1) D1 and the new demand curve (from Question 3) D2. The original demand curve, D1, is shown in blue on the graph below. Now plot the points for this new demand curve, D2, on the graph as well.
