Distance Formula Concepts and Applications

The video tutorial explains how to use the distance formula to find the distance between two points. It covers the formula's application for horizontal, vertical, and diagonal points, emphasizing the importance of subscripts to differentiate between the two points. The tutorial provides a step-by-step guide on subtracting and squaring the coordinates, adding them, and taking the square root to find the distance. An example calculation is demonstrated using specific points to illustrate the process.

What is the primary purpose of the distance formula?

• To find the midpoint between two points

• To find the distance between two points

• To find the slope of a line

• To find the area of a triangle
