persamaan garis yang melalui titik (0,1)dan (1,6) A. x+5y=5 B.x= 5y+1 C. y=5x-5 D. 5x-y+1=0

y-y1 / y2-y1 = x-x1 / x2-x1
y-1 / 6-1 = x-0 / 1-0
y-1 / 5 = x / 1
(y-1). 1 = 5.x
y-1 = 5x
y = 5x + 1
-5x + y - 1 = 0
5x - y + 1 = 0 (D.)

Bab Persamaan Garis
Matematika SMP Kelas VIII

(y - y1) / (y2 - y1) = (x - x1) / (x2 - x1)
(y - 1) / (6 - 1) = (x - 0) / (1 - 0)
(y - 1) / 5 = x/1
y - 1 = 5x
5x - y + 1 = 0
