SUMMARY
The displacement from a position-time graph is calculated as the difference between the final and initial positions. In this discussion, the final position is -15 meters and the initial position is +25 meters, resulting in a displacement of -40 meters. The calculation is definitive: displacement equals final position minus initial position. The participants confirm the calculation and express concerns about potential errors in the answer key.
