Question

what is the distance between points a and b? -6 units -1 units 5 units 6 units

Explanation:

Step1: Identify coordinates

Point A is at - 5 and point B is at 1.

Step2: Use distance formula on number - line

The distance $d$ between two points $x_1$ and $x_2$ on a number - line is $d=\vert x_2 - x_1\vert$. Here, $x_1=-5$ and $x_2 = 1$, so $d=\vert1-(-5)\vert$.

Step3: Simplify the expression

$\vert1-(-5)\vert=\vert1 + 5\vert=\vert6\vert = 6$.

Answer:

6 units
