Full solution stays hidden until you ask for it.
1. Check whether the lines intersect.
2. Look for a 90 degree angle or equivalent slope evidence.
3. Conclude whether the definition of perpendicular lines is satisfied.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
