# How do you find the midpoint of (-4,9) and (1, -3)?

Apr 7, 2016

The midpoint is $= \left(\frac{- 3}{2} , 3\right)$

#### Explanation:

The coordinates are:
(-4 , 9 ) = color(blue)(x_1, y_1

(1 , -3 ) = color(blue)(x_2, y_2

The formula to find the midpoint is :
$\left(\textcolor{b l u e}{\frac{{x}_{1} + {x}_{2}}{2} , \frac{{y}_{1} + {y}_{2}}{2}}\right)$

$= \left(\frac{- 4 + 1}{2} , \frac{9 + \left(- 3\right)}{2}\right)$

$= \left(\frac{- 3}{2} , \frac{6}{2}\right)$

$= \left(\frac{- 3}{2} , 3\right)$
