Exploring the Midpoint Formula and Endpoint Calculation

The video tutorial explains the midpoint formula, which is used to find the midpoint between two points on a coordinate plane. The formula involves averaging the x-coordinates and y-coordinates of the two points. The tutorial provides examples of how to calculate the midpoint and how to find an endpoint when given a midpoint and another endpoint. The process is demonstrated step-by-step, highlighting the importance of understanding the formula as an average of coordinates.

What does the midpoint formula help you find?

• The area of a triangle

• The halfway point between two points

• The slope of a line

• The distance between two points

How do you calculate the x-coordinate of the midpoint?

• Add the x-coordinates and divide by 2

• Divide the first x-coordinate by the second

• Subtract the second x-coordinate from the first

• Multiply the x-coordinates
