One endpoint of a line segment is at (−3, 1).

The line is bisected by placing the midpoint of the line segment at (5, −3).

What are the coordinates of the other endpoint?

 

\(\begin{array}{|lrcll|} \hline \frac{-3+x}{2} &=& 5 \\ -3+x &=& 10 \\ x &=& 13 \\\\ \frac{1+y}{2} &=& -3 \\ 1+y &=& -6 \\ y &=& -7 \\ \hline \end{array}\)

 

The coordinates of the other endpoint is (13, -7)
