Question

what is the coordinate of the midpoint of $overline{uv}$? write your answer as an integer or a decimal, or mixed number in simplest form.

Explanation:

Step1: Identify the coordinates

The coordinate of $U$ is $-75$ and the coordinate of $V$ is $-70$.

Step2: Apply mid - point formula

The mid - point formula for two points $x_1$ and $x_2$ on a number line is $\frac{x_1 + x_2}{2}$. Here $x_1=-75$ and $x_2 = - 70$. So, $\frac{-75+( - 70)}{2}=\frac{-75 - 70}{2}=\frac{-145}{2}=-72.5$.

Answer:

$-72.5$
