gardien garis yang melalui titik p -3,2 dan q 4,-2 adalah

m = (y - y1) / (y2 - y1) = (x - x1) / (x2 - x1)
m = (y - 2) / (-2 - 2) = (x + 3) / (4 + 3)
m = (y - 2) / -4 = (x + 3) / 7
m = 7 (y - 2) = -4 (x + 3)
m = 7y - 14 = -4x - 12
m = 7y - 14 + 4x + 12 = 0
m = 7y + 4x - 14 + 12 = 0
m = 7y + 4x - 2 = 0
