# Midpoint Formula

## Formula

### Summary

This formula calculates the midpoint of a line defined by two points in the cartesian coordinate system.

Expression Description
The midpoint
The coordinates of the first point
The coordinates of the second point

## Usage

To calculate the midpoint of a line defined by two points, average the x-coordinates of the two points together to get the x-coordinate of the midpoint. Then average the y-coordinates of the points together to get the y-coordinate of the midpoint.

### Midpoint of Line With Points (3, 1) and (7, 5)

This example demonstrates how to find the midpoint of a line defined by the two points (3,1) and (7,5). The steps are shown below:

1. Set up the formula and subsitute the coordinates of the points of the line.

3. Evaluate the division expressions.

4. The midpoint of the line is at the point .

### Midpoint of Line With Points (2, 5) and (6, 1)

This example demonstrates how to find the midpoint of a line defined by the two points (2,5) and (6,1). The steps are shown below:

1. Set up the formula and subsitute the coordinates of the points of the line.
