[tex] \frac{P - P_{1}}{P_{2}-P_{1}} [/tex] = [tex] \frac{Q - Q_{1}}{Q_{2}-Q_{1}} [/tex]
[tex] \frac{P - 7500}{8000 - 7500} [/tex] = [tex] \frac{Q - 2000}{1500 - 2000} [/tex]
[tex] \frac{P - 7500}{500} [/tex] = [tex] \frac{Q - 2000}{-500} [/tex]
500Q - 1.000.000 = -500P + 3.750.000
                   500Q = -500P + 4.750.000
                       Qd = -P + 9500
