  1. Hi Waseem,
    You don’t have to show -0.4 in the P axis. For your equation, the supply curve will begin at a quantity of 200. This supply equation is highly unrealistic, as it indicates that even if the price of the good were zero, firms would still produce 200 units. This makes almost no sense. Most supply equations will have a ‘c’ variable that is negative, indicating that the Q intercept is negative. In you case, the P-intercept is negative.

    Hope that helps.

  2. How to draw the the graph of equation
    Qs=200+500P
    0=200+500P
    500P=-200
    P=-0.4

    If P=0
    Qs=200

    Can we show -0.4 in y-axis
    Please if you can support in plotting this equattion graph.
