Distance Between Two Points

Mr. Buffington introduces the concept of finding the distance between two points on a graph using the Pythagorean theorem. He explains how to calculate the distance using coordinate changes and provides examples with both positive and negative coordinates. The lesson emphasizes that distance is always a positive measurement and demonstrates the process through various examples.
