Walkthrough
Full solution stays hidden until you ask for it.
1. Compute or identify each slope.
2. Check for negative reciprocal relationship or horizontal/vertical pair.
3. Conclude perpendicular.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
