Tentukan persamaan garis lurus melalui titik (3,-2) dan (-1,4)!

Bab Persamaan Garis
Matematika SMP Kelas VIII

(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y - (-2))/(4 - (-2)) = (x - 3)/(-1 - 3)
(y + 4)/6 = (x -3)/-4
-4 . (y + 4) = 6 . (x - 3)
-4y - 16 = 6x - 18
6x + 4y = 18 - 16
6x + 4y = 2
3x + 2y = 1
