Full solution stays hidden until you ask for it.
1. Compare the two slopes.
2. Equal slopes mean distinct lines are parallel.
3. Unequal slopes mean the lines are not parallel.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using negative reciprocal slopes for parallel lines.
