    \[P=0 => Q=30 (Q,P)= (30,0) , P=30 => Q=0 =>(0,30)\]

    This last reply was more mathematical than explanatory. First assume that P is on the Y-axis and Q is on the VX-axis which would be true if you were starting to drawn either a Demand or Supply curve. I would suggest that first when Q=0, then P = 30, so plot that point (0,30) on the X,Y plane. Then when P=0, then Q= 30 so plot that ooint as (30,0) and connect the two points. You have your graph. wmw
