persamaan garis yang melalui titik (5,-3) dan sejajar garis 2y+4x-8=0

Kelas 8 Matematika
Bab Persamaan Garis

ax + by + c = 0, sejajar, (p, q)
ax + by = ap + bq

4x + 2y - 8 = 0, sejajar, (5, -3)
4x + 2y = 4 . 5 + 2 . (-3)
4x + 2y = 20 - 6
4x + 2y = 14
2x + y = 7

2y +4x -8 = 0
m = -a/b = -4/2 = -2

y - y1 = m(x-x1)
y +3 = -2(x-5)
y +3 = -2x +10
y = -2x +10 -3
y = -2x +7
