Use the midpoint formula to find the midpoint of the line segment.

$(\frac{x_{1} + x_{2}}{2}, \frac{y_{1} + y_{2}}{2})$

Substitute in the values for $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ .

$(\frac{7 + 0}{2}, \frac{9 + 3}{2})$

Add $7$ and $0$ to get $7$ .

$(\frac{7}{2}, \frac{9 + 3}{2})$

Add $9$ and $3$ to get $12$ .

$(\frac{7}{2}, \frac{12}{2})$

Divide $12$ by $2$ to get $6$ .
