Parallel and Perpendicular Lines

Eight exam-style questions on parallel and perpendicular lines. Whenever you're stuck, you have four kinds of help, in this order:

🤔 Socratic prompt — a question to get you thinking (tap again for a more specific one). 💡 Hint — a piece of method. ✅ Check my answer — try as many times as you like; you'll get diagnostic feedback. 👀 Worked solution — the full method, unlocked once you've genuinely tried.

Give gradients as fractions or decimals (both accepted). For "general form" answers, use integer coefficients with the leading term positive, e.g. 3x − y − 5 = 0.

💛 Reflection

Before you close this, take a moment:

When you needed a perpendicular gradient, did you remember both the flip and the sign change every time? Where did a slip nearly happen?
Did rearranging a line into y = mx + c to read off its gradient feel automatic, or is it still worth slowing down for?
If you taught one of these questions to a friend, which would you choose, and why?
