The formula of a midpoint of the segment between the points
[tex](x_1,\ y_1),\ (x_2,\ y_2)\\\\M\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)[/tex]
We have:
[tex](17,\ -11),\ (-14,\ -16)[/tex]
Substitute:
[tex]M\left(\dfrac{17+(-14)}{2},\ \dfrac{-11+(-16)}{2}\right)\to M\left(\dfrac{3}{2},\ \dfrac{-27}{2}\right)[/tex]
Answer: B.
