# How do you find the midpoint of (1.8, –3.4) and (–0.4, 1.4)?

Oct 27, 2014

You can find it out using the mid point formula, which is given by:

$M \left(x , y\right) = \left(\frac{{x}_{1} + {x}_{2}}{2} , \frac{{y}_{1} + {y}_{2}}{2}\right)$
where:
$\left(x , y\right)$ are coordinates of the midpoint,
${x}_{1} \mathmr{and} {x}_{2}$ are the $x$-coordinates of the given points,
and ${y}_{1} \mathmr{and} {y}_{2}$ are their respective $y$-coordinates.

Substituting the given values in the formula:
$M \left(x , y\right) = \left(\frac{1.8 + \left(- 0.4\right)}{2} , \frac{- 3.4 + 1.4}{2}\right)$
$M \left(x , y\right) = \left(\frac{1.4}{2} , - \frac{2}{2}\right)$
$M \left(x , y\right) = \left(0.7 , - 1\right)$
