Understanding the Distance Formula

The video tutorial explains how to determine the length of a segment on the coordinate plane. It begins by labeling the endpoints and introduces the distance formula, which is derived from the Pythagorean theorem. The tutorial demonstrates how to apply the formula to calculate the segment length and simplifies the result to find the approximate distance.

What is the first step in determining the length of a segment on the coordinate plane?

• Find the slope of the segment.

• Draw a perpendicular bisector.

• Label the endpoints of the segment.

• Calculate the midpoint of the segment.
