Question

The midpoint of segment_UV is (5, –11). The coordinates of one endpoint are U(3, 5). Find the coordinates of endpoint V

Answer 1

The \(x\) coordinate of the midpoint is the mean of the \(x\)-coordinates.
The \(y\) coordinate of the midpoint is the mean of the \(y\)-coordinates.

Answer 2

For the \(x\) coordinate of \(V\), solve the equation:\[{x + 3 \over 2} = 5\]
