Question

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

Explanation:

Step1: Identify the coordinates

The coordinate of $W$ is $- 1$ and the coordinate of $X$ is $2$.

Step2: Apply mid - point formula

For two points $a$ and $b$ on a number line, the mid - point $M$ is given by $M=\frac{a + b}{2}$. Here $a=-1$ and $b = 2$, so $M=\frac{-1+2}{2}$.

Step3: Calculate the value

$\frac{-1 + 2}{2}=\frac{1}{2}=0.5$

Answer:

$0.5$
