Full solution stays hidden until you ask for it.
1. Compute the slope of each segment.
2. Check for negative reciprocal slopes or horizontal/vertical pairing.
3. Conclude the segments are perpendicular.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Equal slopes as perpendicular.
