[tex] \frac{P - P_{1}}{P_{2}-P_{1}} [/tex] = [tex] \frac{Q - Q_{1}}{Q_{2}-Q_{1}} [/tex]
[tex] \frac{P - 7000}{8000-7000} [/tex] = [tex] \frac{Q - 200}{400-200} [/tex]
[tex] \frac{P - 7000}{1000} [/tex] = [tex] \frac{Q - 200}{200} [/tex]
1000Q - 200.000 = 200P - 1.400.000
1000Q = 200P - 1.200.000
Q = [tex] \frac{1}{5} [/tex]P - 1200
