Find the Midpoint (-3,-1) , (-11,3)

$(- 3, - 1)$ , $(- 11, 3)$

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

$(\frac{- 3 - 11}{2}, \frac{- 1 + 3}{2})$

Subtract $11$ from $- 3$ .

$(\frac{- 14}{2}, \frac{- 1 + 3}{2})$

Divide $- 14$ by $2$ .

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

Add $- 1$ and $3$ .

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

Divide $2$ by $2$ .

$(- 7, 1)$
