Question

example 2 find the length of a segment try it! 2. refer to the figure shown. a. what is jk?

Explanation:

Step1: Identify the coordinates

The coordinate of point $J$ is 5 and the coordinate of point $K$ is 12.

Step2: Use the distance formula for a number - line

The distance between two points on a number - line is given by $d=\vert x_2 - x_1\vert$. Here, $x_1 = 5$ and $x_2=12$. So, $JK=\vert12 - 5\vert$.

Step3: Calculate the value

$\vert12 - 5\vert=7$.

Answer:

7
