Question

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

Explanation:

Step1: Identify the coordinates

Let the coordinate of $J$ be $x_1 = 3$ and the coordinate of $K$ be $x_2=5$.

Step2: Apply mid - point formula

The mid - point formula for a one - dimensional line segment with endpoints $x_1$ and $x_2$ is $\text{Midpoint}=\frac{x_1 + x_2}{2}$. Substitute $x_1 = 3$ and $x_2 = 5$ into the formula: $\frac{3+5}{2}=\frac{8}{2}=4$.
