persamaan garis yang melalui titik A(-2,-2) dan B(4,-6) adalah.?

Kelas 8 Matematika
Bab Persamaan Garis

(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y + 2)/(-6 + 2) = (x + 2)/(4 + 2)
(y + 2)/(-4) = (x + 2)/6
6 (y + 2) = (-4) . (x + 2)
6y + 12 = -4x - 8
4x + 6y + 12 + 8 = 0
4x + 6y + 20 = 0
2x + 3y + 10 = 0
