#### Answer

$(\frac{3}{2},0)$

#### Work Step by Step

We are given that the midpoint $M$ of a line segment $PQ$ with endpoints ($x_{1}$,$y_{1}$) and ($x_{2}$,$y_{2}$) is equal to:
$M=(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})$
Therefore, $M=(\frac{4+(-1)}{2},\frac{-3+3}{2})=(\frac{4-1}{2},\frac{0}{2})=(\frac{3}{2},0)$.
