Step 1

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

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

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

Step 2

Substitute in the values for

(x_{1}, y_{1})

$(x_{1}, y_{1})$ and

(x_{2}, y_{2})

$(x_{2}, y_{2})$ .

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