plizzzz buat bsok.......

y + 2x - 3 = 0
3x + y + 5 = 0
Kurang kan
-x - 8 = 0
x = -8
y = 3 - 2x = 3 - 2(-8) = 19

Titik potong = A = (-8,19) ✓

Garis h : 2y- x - 4 = 0
gradien garis h = mh = -a/b = -(-1)/2 = 1/2

garis k sejajar garis h
mk = mh = 1/2 ✓

Persamaan garis k, dg m = 1/2 melalui (x1,y1) = (-8,19)
y - y1 = m(x - x1)
y - 19 = 1/2 (x + 8)
Kali silang
2y - 38 = x + 8
x - 2y + 38 + 8 = 0
x - 2y + 46 = 0 ✓
