4y = -3x +8
y = -3/4x +8
maka, m₁ =-3/4
m₁ . m₂ = -1
-3/4 . m₂ = -1
m₂ = -1 per -3/4
m₂ = 4/3
y -y₁ = m(x -x₁)
y -(-4) = 4/3(x -2)
y +4 = 4/3x -8/3 dikali 3 untuk menghilangkan penyebut, sehingga
3y +12 = 4x -8
3y = 4x -8 -12
3y = 4x -20
4x -3y -20 = 0
3x + 4y = 8
y = -3/4 x + 8, m1 = -3/4
m2 = 4/3
persamaan garisnya
y-y1 = m2(x-x1)
y- (-4) = 4/3 (x-2)
y = 4/3x -8/3 - 4
y = 4/3x - 20/3
3y = 4x - 20
jadi persamaan garisnya adalah 3y = 4x -20
