Question

find the location of q, the midpoint of $overline{pr}$. location of q:

Explanation:

Step1: Identify coordinates

The coordinate of $P$ is $- 10$ and the coordinate of $R$ is $2$.

Step2: Apply mid - point formula

The mid - point formula for two points $x_1$ and $x_2$ on a number line is $Q=\frac{x_1 + x_2}{2}$. Here $x_1=-10$ and $x_2 = 2$, so $Q=\frac{-10 + 2}{2}$.

Step3: Calculate the value

$\frac{-10 + 2}{2}=\frac{-8}{2}=-4$.

Answer:

$-4$
