The midpoint is given by the following formula:
[tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]Where (x1,y1) and (x2,y2) are the coordinates of the endpoints of the segment.
Replace the given values in the formula and solve for M:
[tex]\begin{gathered} M=(\frac{14+(-9)}{2},\frac{7+1}{2}) \\ M=(\frac{5}{2},\frac{8}{2}) \\ M=(2.5,4) \end{gathered}[/tex]The coordinates of the midpoint are M(2.5,4)
