Find the Midpoint (-3,9) , (0,9)

$(- 3, 9)$ , $(0, 9)$

Step 1

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

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

Step 2

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

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

Step 3

Add $- 3$ and $0$ .

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

Step 4

Move the negative in front of the fraction.

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

Step 5

Add $9$ and $9$ .

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

Step 6

Divide $18$ by $2$ .

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