What is the Distance Formula?
The distance between two points (x1, y1) and (x2, y2) is given by the formula:

$$D = \sqrt {{{\left( {{x_2} - {x_1}} \right)}^2} + {{\left( {{y_2} - {y_1}} \right)}^2}}$$

This video shows how the distance formula comes from the Pythagorean Theorem, and do one simple example of finding the distance between two points.
