Question

find the location of n, the midpoint of $overline{mp}$. location of n:

Explanation:

Step1: Identify the coordinates

The coordinate of $M$ is $- 9$ and the coordinate of $P$ is $5$.

Step2: Apply mid - point formula

The mid - point formula for two points $x_1$ and $x_2$ on a number line is $N=\frac{x_1 + x_2}{2}$. Here $x_1=-9$ and $x_2 = 5$. So $N=\frac{-9 + 5}{2}$.

Step3: Calculate the value

$\frac{-9 + 5}{2}=\frac{-4}{2}=-2$.

Answer:

$-2$
