Question

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

Explanation:

Step1: Identify the coordinates

The coordinate of point $P$ is $- 10$, and the coordinate of point $Q$ is $5$.

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 $x_1=-10$ and $x_2 = 5$. So, $\frac{-10 + 5}{2}=\frac{-5}{2}=-2.5$.

Answer:

$-2.5$
