38) 3x + 4y = 6
4y = - 3x + 6
m = - ¾
sejajar m1 = m2 = - ¾
pers garis
y - y1 = m ( x - x1)
y - 6 = - ¾ ( x + 2)
y = - ¾ x - 3/2 + 6 ( dikali 4)
4y = - 3x - 6 + 24
4y + 3x = 18
3x + 4y = 18 ( D )
39) 4x - 4y + 10 = 0
- 4y = - 4x - 10
m = - 4/- 4
m = 1
sejajar m1 = m2 = 1
y - y1 = m ( x - x1 )
y - 5 = 1 ( x + 2)
y = x + 2 + 5
y = x + 7
y - x - 7 = 0 ( C )
