2y=-3x+5
y=(-3x+5)/2
3x+2[(-3x+5)/2] -5=0
3x(-6x+10)/2 +5=0
3x-3x+5+5=0
x=-10
2y = -3x +5
y = -3/2x +5/2
Maka, m₁ = -3/2
m₁ . m₂ = -1
-3/2 . m₂ = -1
m₂ = -1 per -3/2
m₂ = 2/3
y -y₁ = m(x -x₁)
y -3 = 2/3(x -0)
y -3 = 2/3x dikali 3 untuk menghilangkan penyebut, sehingga
3y -9 = 2x
2x -3y +9 = 0
Itu jawabannya.
