Answer 1

Rumus => P-P1/P2-P1 = Q-Q1/Q2-Q1 .. Masukin ke rumus .. sehingga :
=> P-10/20-10 = Q-500/400-500
=> P-10/10 = Q-500/-100 (dikalikan silang)
=> P-10(-100) = Q-500(10)
=> -100P+1000 = 10Q-5000
=> -100P = 10Q-5000-1000
=> -100P = 10Q-6000 (dibagi -100)
=> P = 60 - 0,1 Q

Fungsi permintaannya adalah P = 60 - 0,1 Q
