y-(-6) = -1/-3(x-4)
y+6 = 1/3(x-4)
y+6 = 1/3x -4/3
y = 1/3x -4/3 -6
y =1 per 3x -22 per 3
m = -3
Karena tegak lurus, maka gradiennya berbeda dengan hasil kali -1 :
m₂ = -1 : m
= -1 : -3
= 1/3
Lalu, kita cari persamaan garisnya menggunakan rumus cepat :
y = m₂x - ( m₂x₁ - y₁ )
y = 1/3x - ( 4/3 + 6 )
y = 1/3x - 22/3
3y = x - 22
x - 3y - 22 = 0
