(-6, 0) dan (0,3)
(y - y1) / (y2 - y1) = (x - x1) / (x2 - x1)
(y - 0) / (3 - 0) = (x - (-6)) / (0 - (-6))
6y = 3 (x + 6)
6y = 3x + 18
3x - 6y + 18 = 0
ax + by = 0, tegak lurus, (p, q)
bx - ay = bp - aq
3x - 6y + 18 = 0, tegak lurus, (-6, 0)
-6x - 3y = -6 . (-6) - 3 . 0
-6x - 3y - 36 = 0
2x + y + 12 = 0
y = -2x - 12
