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
