🌌 Star Route

👉 Mission Rules:
🛸 【Escort】: Parallel to asteroid belt. Parallel lines have "exactly equal" slopes (m₁ = m₂).
🛡️ 【Shield Break】: Break enemy shield. Perpendicular lines have "negative reciprocal" slopes (m₁ × m₂ = -1).
🌌 【Stargate】: Horizontal and vertical lines. Watch out for slope 0 and undefined slope!

⚠️ Incorrect predictions cause mission failure. Set slopes precisely!
