(P-P1) / (P2-P1) = (Q-Q1) / (Q2-Q1)
(P-85000)/(65000-85000)=(Q-7750)/(6750-7750)
(P-85000) / (-20000) = (Q-7750) / (-1000)
-1000(P-85000) = -20000(Q-7750)
-1000P+85000000 = -20000Q+155000000
20000Q = 155000000-85000000+1000P
20000Q = 70000000+1000P
Q = 3500+0,05P
Jadi fungsi permintaannya adalah
Q = 1/20P+3500 (E)
Semoga membantu
