Penjelasan dengan langkah-langkah:
m1 = (y2 - y1)/(x2 - x1)
m1 = (6 - 2)/(-3 - 5)
m1 = 4/-8
m1 = -1/2
******************************************************************
Tegak lurus
m1 . m2 = -1
-1/2 . m2 = -1
m2 = -1 . -2/1
m2 = 2
y - y1 = m2 . (x - x1)
y - 4 = 2 . (x + 3)
y - 4 = 2x + 6
2x - y = -4 - 6
2x - y = -10
