(- 3, 9)

$(- 3, 9)$ ,

(0, 9)

$(0, 9)$

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{- 3 + 0}{2}, \frac{9 + 9}{2})

$(\frac{- 3 + 0}{2}, \frac{9 + 9}{2})$

Step 3

Add

- 3

$- 3$ and

0

$0$ .

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

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

Step 4

Move the negative in front of the fraction.

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

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

Step 5

Add

9

$9$ and

9

$9$ .

(- \frac{3}{2}, \frac{18}{2})

$(- \frac{3}{2}, \frac{18}{2})$

Step 6

Divide

18

$18$ by

2

$2$ .

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

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