Question

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

Explanation:

Step1: Identify the coordinates

The coordinate of point $G$ is $4$ and the coordinate of point $H$ is $8$.

Step2: Apply mid - point formula

The mid - point formula for two points on a number line with coordinates $x_1$ and $x_2$ is $\frac{x_1 + x_2}{2}$. Here $x_1=4$ and $x_2 = 8$, so the mid - point is $\frac{4 + 8}{2}$.

Step3: Calculate the value

$\frac{4+8}{2}=\frac{12}{2}=6$.

Answer:

$6$
