The formula for the midpoint of a line segment:

((x_1+x_2)/(2),(y_1+y_2)/(2))
where x₁, y₁ - the coordinates of one endpoint; x₂, y₂ - the coordinates of the other endpoint


\hbox{endpoint} - (5,1) \\ x_1=5 \\ y_1=1 \\ \\ \hbox{midpoint} - (9,3) \\ \Downarrow \\ (5+x_2)/(2)=9 \\ 5+x_2=18 \\ x_2=13 \\ \\ (1+y_2)/(2)=3 \\ 1+y_2=6 \\ y_2=5 \\ \\ \hbox{the other endpoint} - \boxed{(13,5)}
