Pepersamaan garis yang melalui titik (8,5) dan (-2,7) adalah A.5y-x+33=0 B. Y+5x-33=0 C.5y+x-33 =0 D.y-5x+33=0

(y-y1) / (y2 -y1) = (x-x1) / (x2-x1)
titik (8,5) = (x1,y1)
titik (-2,7) = (x2,y2)

(y-5) / (7-5) = (x-8) / (-2-8)
(y-5) / 2 = (x-8) / (-10)
(-10) (y-5) = 2(x-8)
-10y + 50 = 2x -16
2x + 10y -66 =0 (di bagi 2)
x + 5y -33 =0 atau 5y + x -33 =0
