Find the Midpoint (-1,3) and (-9,-7)

$(- 1, 3)$ and $(- 9, - 7)$

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

$(\frac{- 1 - 9}{2}, \frac{3 - 7}{2})$

Subtract $9$ from $- 1$ .

$(\frac{- 10}{2}, \frac{3 - 7}{2})$

Divide $- 10$ by $2$ .

$(- 5, \frac{3 - 7}{2})$

Subtract $7$ from $3$ .

$(- 5, \frac{- 4}{2})$

Divide $- 4$ by $2$ .

$(- 5, - 2)$
