5y=15-3x
y=3-3/5x
gradiennya -3/5 (m=-3/5)
sejajar, maka gradiennya sama
y-y1=m(x-x1)
y-3=-3/5(x-2)
5y-15=-3x+6
5y+3x=6+15
5y+3x=21
5y = -3x +15
y = -3/5x +15/5
y = -3/5x +3
maka, m = -3/5
y -y₁ = m(x -x₁)
y -3 = -3/5(x -2)
y -3 = -3/5x +6/5 dikali 5 untuk menghilangkan penyebut, sehingga
5y -15 = -3x +6
5y = -3x +6 +15
5y = -3x +21
3x +5y -21 = 0
