find the distance between k and l on the number line below.
find the distance between k and l on the number line below.
Answer
Explanation:
Step1: Identify coordinates
The coordinate of $K$ is $- 10$, and the coordinate of $L$ is $-1$.
Step2: Use distance formula
The distance $d$ between two points $a$ and $b$ on a number - line is $d=\vert a - b\vert$. Here, $a=-10$ and $b = - 1$, so $d=\vert-10-(-1)\vert=\vert-10 + 1\vert=\vert-9\vert$.
Step3: Evaluate absolute - value
$\vert-9\vert = 9$.
Answer:
$9$
