tolong dibantu yaa besok dikumpulin

A(0,3) dan B(6,0)
(y - 0)/(3 - 0) = (x - 6)/(0 - 6)
=> y/3 = (x - 6)/(-6)
=> y(-6) = (x - 6)(3)
=> -6y = 3x - 18
=> 3x + 6y = 18 (: 3)
=> x + 2y = 6

a(2,1) dan b(5,6)
(y - 6)/(1 - 6) = (x - 5)/(2 - 5)
=> (y - 6)/(-5) = (x - 5)/(-3)
=> (y - 6)(-3) = (x - 5)(-5)
=> -3y + 18 = -5x + 25
=> 5x - 3y = 25 - 18
=> 5x - 3y = 7
