Find the Midpoint (-10,2) and (-5,-1)

$(- 10, 2)$ and $(- 5, - 1)$

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

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

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

$(\frac{- 10 - 5}{2}, \frac{2 - 1}{2})$

Subtract $5$ from $- 10$ .

$(\frac{- 15}{2}, \frac{2 - 1}{2})$

Move the negative in front of the fraction.

$(- \frac{15}{2}, \frac{2 - 1}{2})$

Subtract $1$ from $2$ .

$(- \frac{15}{2}, \frac{1}{2})$
