[tex] \frac{7 - ( - 3)}{ - 12 - ( - 8)} [/tex]
[tex] \frac{10}{ - 4} [/tex]

Persamaan Garis
P(-12,7)
Q(-3,-8)
gradien garis melalui PQ = m1 = ∆y/∆x
m1 = (7 - (-8)) / (-12 - (-3))
m1 = 15/-9
m1 = -5/3
syarat tegak lurus → m1 × m2 = -1
gradien garis yg tegak lurus garis PQ = m2
m2 = -1/m1
m2 = -1/(-5/3)
m2 = 3/5
