# How do you find the midpoint of (-1,4) and (-2,-9)?

Feb 17, 2016

The mid point $= \left(- 1.5 , - 2.5\right)$

#### Explanation:

The coordinates are:
(-1,4) = color(blue)(x_1,y_1

(-2,-9) = color(blue)(x_2,y_2

The mid point is found using formula:
$\frac{{x}_{1} + {x}_{2}}{2} , \frac{{y}_{1} + {y}_{2}}{2}$

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

$= \frac{- 3}{2} , \frac{- 5}{2}$

$= \left(- 1.5 , - 2.5\right)$
