Question

incorrect. your answer is incorrect. find the location of q, the mid - point of $overline{pr}$. location of q: try one last time

Explanation:

Step1: Identify the coordinates of P and R

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

Step2: Use the 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 \(Q=\frac{-10+( - 2)}{2}=\frac{-10 - 2}{2}=\frac{-12}{2}=-6\).

Answer:

-6
