= 3x+4y dari 4x - 3y + 8 = 0, (posisi 4 & 3 di tukar dan tanda negatif diubah menjadi positif)
= 3(2) + 4(-7)
= 6 - 28
= -22
3x+4y=-22
3x+4y+22=0
x1= 2 y1= -7
4x - 3y + 8= 0 diubah menjadi -3y= -4x - 8
-3y= -4x - 8
y= -4/-3
y= 4/3 atau m1= 4/3
tega lurus :
m1 × m2= -1
4/3 × m2= -1
m2= -1 : 4/3
m2= -1 × 3/4
m2= -3/4
y-y1= m2(x-x1)
y-(-7)= -3/4(x-2)
y+7= -3/4x + 6/4
y= -3/4x + 6/4 - 7
4y= -3x + 6 - 28
4y= -3x - 22
atau
3x + 4y + 22= 0
