Example Question #1 : How To Find The Endpoints Of A Line Segment
A line segment on the coordinate plane has midpoint . One of its endpoints is
. What is the
-coordinate of the other endpoint, in terms of
and/or
?
Let be the
-coordinate of the other endpoint. Since the
-coordinate of the midpoint of the segment is the mean of those of the endpoints, we can set up an equation as follows:
Example Question #296 : Geometry
A line segment on the coordinate plane has one endpoint at ; its midpoint is
. Which of the following gives the
-coordinate of its other endpoint in terms of
and
?
To find the value of the -coordinate of the other endpoint, we will assign the variable
. Then, since the
-coordinate of the midpoint of the segment is the mean of those of its endpoints, the equation that we can set up is
.
We solve for :
