Using a hint is okay. It just tells the trainer to give you a little more review.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Check whether the lines are coplanar.
2. Determine whether the full lines intersect.
3. Apply the definition of parallel lines.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying all nonintersecting 3D lines are parallel.
