Garis PQ melalui titik (5 , -7 ) dan sejajar dengan garis 2x + 3y + 5 = 0 . Tentukan persamaan garis PQ

Bab Persamaan Garis
Matematika SMP Kelas VIII

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

2x + 3y + 5 = 0
2x + 3y = -5, sejajar, (5, -7)
2x + 3y = 2 . 5 + 3 . (-7)
2x + 3y = 10 - 21
2x + 3y = - 11
2x + 3y + 11 = 0
