Understanding the Distance Formula

The video tutorial explains how to use the distance formula to find the distance between two points on a graph. It begins by graphing points X and Y, then labeling them as ordered pairs. The tutorial demonstrates substituting these values into the distance formula and simplifying the equation to find the distance. The process includes careful attention to signs and arithmetic operations, resulting in the final distance calculation.

What is the initial step in using the distance formula?

• Graphing the points on a coordinate plane

• Calculating the midpoint

• Determining the angle between points

• Finding the slope
