Using the distance formula to determine the distance between two coordinate points

The video tutorial explains how to calculate the distance between two coordinate points using the Pythagorean theorem. It begins with an introduction to the concept, followed by plotting the points on a graph. The instructor then sets up the distance formula, emphasizing the importance of handling negative signs correctly. The formula is simplified step by step, leading to the final calculation of the distance. The tutorial concludes with a verification of the result.
