↔ Persamaan Garis 1 → 3y - 5x + 15 = 0
↔ Titik Yang Dilewati Garis 2 → (x₁, y₁) → (6, -4)
≡ Penyelesaian:
⇔ Tentukan Gradien (m):
⇒ 3y - 5x + 15 = 0
⇒ m₁ = -x / y
⇒ m₁ = -(-5) / 3
⇒ m₁ = ⁵/₃
Karena Kedua Garis Sejajar, Maka m₁ = m₂ = ⁵/₃
⇔ Menentukan Persamaan Garis 2:
⇒ y - y₁ = m₂ (x - x₁)
⇒ y - (-4) = ⁵/₃ (x - 6) [×3]
⇒ 3(y + 4) = 5(x - 6)
⇒ 3y + 12 = 5x - 30
⇒ 5x - 3y - 42 = 0
