What Is the Equation for a Midpoint?


Quick Answer

The equation to determine the midpoint is expressed as the sum of x1 and x2 divided by two for the x-coordinate and the sum of y1 and y2 divided by two for the y-coordinate. This formula can also be described as finding the average between each point.

For example, to find the midpoint between the points (4, 9) and (6, 3), the equation requires adding 4 and 6 for a sum of 10 and then dividing this sum by 2 for the x-coordinate point of the midpoint, which is 5. Similarly, the y-coordinate point of the midpoint is found by adding 9 and 3 for a sum of 12, and then dividing 12 by 2, yielding a y-coordinate midpoint of 6.
