Question

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

Explanation:

Step1: Identify coordinates

$P=-12$, $R = - 2$

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 $x_1=-12$ and $x_2=-2$, so $Q=\frac{-12+( - 2)}{2}=\frac{-12 - 2}{2}=\frac{-14}{2}=-7$

Answer:

$-7$
