-$( 8 , - 2 ) , ( - 1,1 )$
A) $( 9 , - 3 )$
B) $( 7 , - 1 )$
C) $\left( \frac { 7 } { 2 } , - \frac { 1 } { 2 } \right)$
D) $\left( \frac { 9 } { 2 } , - \frac { 3 } { 2 } \right)$

The midpoint formula is $\left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right)$. Substituting the given points, $(8, -2)$ and $(-1, 1)$, we get $\left( \frac{8 + (-1)}{2}, \frac{-2 + 1}{2} \right) = \left( \frac{7}{2}, -\frac{1}{2} \right)$.
