Example Question #21 : Midpoint Formula
Find the midpoint of a line segment that has endpoints at and .
Recall the formula for finding a midpoint of a line segment:
The coordinates of the midpoint is just the average of the x-coordinates and the average of the y-coordinates.
Plug in the given points to find the midpoint of the line segment.

Recall how to find the midpoint of a line segment with endpoints at and :
Example Question #24 : Midpoint Formula
A line segment on the coordinate plane has its endpoints at and .
True or false: Its midpoint is located at .
True
False
False
The midpoint of a line segment with endpoints and is located at .
Set , and evaluate both expressions:
The midpoint is at , so the statement is false.
Example Question #1 : How To Find The Endpoints Of A Line Segment
Find the midpoint between the points:
and
The midpoint formula is
So for our two points the equation is
Example Question #1 : How To Find The Endpoints Of A Line Segment
What is the midpoint between the two points:
and
The midpoint formula is
If we plug in our points we get
Example Question #21 : Lines
What is the midpoint between the two points:
and
The midpoint formula is
So lets plug in our two points, that gives us
Example Question #4 : How To Find The Endpoints Of A Line Segment
What is the midpoint between the two points:
and
The equation to find the midpoint between two points is
If we plug in our values of the two points we get
Example Question #5 : How To Find The Endpoints Of A Line Segment
One of the endpoints of a line is and the midpoint is . What is the other endpoint?
The midpoint's coordinates are the average of the endpoints'.
This means that the x-coordinates of the two endpoints have a mean of 1:
multiply both sides by 2
subtract 8
this means the other endpoint's x-coordinate is -6
This also means that the y-coordinates of the two endpoints have a mean of -3:
multiply both sides by 2
add 7 to both sides
The coordinate pair that we're looking for is (-6, 1)
Example Question #22 : Lines
The midpoint of a line is and one of the endpoints is . What is the other endpoint?
The midpoint's coordinates are just the mean of the endpoints'.
This means that the mean of the two x-coordinates is 9:
multiply both sides by 2
subtract 1
This also means that the mean of the two y-coordinates is 9:
multiply both sides by 2
subtract 17
So the other endpoint we were solving for is
