This video tutorial explains how to determine the distance between two points using the distance formula, derived from the Pythagorean Theorem. It provides a step-by-step example calculation, including converting the result into simplified radical form and visualizing the process graphically.

What is the formula used to calculate the distance between two points on a plane?

• The sum of the x-coordinates and y-coordinates

• The square root of the sum of the squares of the differences in x and y coordinates

• The product of the x-coordinates and y-coordinates

• The difference between the x-coordinates and y-coordinates
