$(- \frac{4}{3}, \frac{1}{3})$ and $(- \frac{8}{3}, - \frac{7}{3})$

Step 1

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

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

Step 2

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

$(\frac{- \frac{4}{3} - \frac{8}{3}}{2}, \frac{\frac{1}{3} - \frac{7}{3}}{2})$

Step 3

Step 3.1

Combine the numerators over the common denominator.

$(\frac{\frac{- 4 - 8}{3}}{2}, \frac{\frac{1}{3} - \frac{7}{3}}{2})$

Step 3.2

Subtract $8$ from $- 4$ .

$(\frac{\frac{- 12}{3}}{2}, \frac{\frac{1}{3} - \frac{7}{3}}{2})$

Step 3.3

Divide $- 12$ by $3$ .

$(\frac{- 4}{2}, \frac{\frac{1}{3} - \frac{7}{3}}{2})$

Step 4

Divide $- 4$ by $2$ .

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