Full solution stays hidden until you ask for it.
1. Convert zeros to factors.
2. Include a scale factor a.
3. Substitute the point to solve for a.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Missing scale factor when the unscaled factors do not pass through the point.
