Question

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

Explanation:

Step1: Identify coordinates

The coordinate of point $D$ is $- 1$ and of point $E$ is $5$.

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 $x_1=-1$ and $x_2 = 5$, so $\frac{-1 + 5}{2}$.

Step3: Calculate the result

$\frac{-1+5}{2}=\frac{4}{2}=2$.

Answer:

$2$
