we know that
The coordinates of the midpoint between two points is equal to
[tex]M=(\frac{x1+x2}{2}, \frac{y1+y2}{2})[/tex]
In this problem we have
[tex](x1,y1)=A(-2,3)[/tex]
[tex](x2,y2)=B(1,8)[/tex]
Substitute the values in the formula
[tex]M=(\frac{-2+1}{2}, \frac{3+8}{2})[/tex]
[tex]M=(-\frac{1}{2}, \frac{11}{2})[/tex]
therefore
the answer is the option
[tex]M=(\frac{-2+1}{2}, \frac{3+8}{2})[/tex]
