Question

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

Explanation:

Step1: Identify coordinates

Let the coordinate of point A be - 4 and point B be 1.

Step2: Use distance formula

The distance $d$ between two points $x_1$ and $x_2$ on a number - line is $d=\vert x_2 - x_1\vert$. Here, $x_1=-4$ and $x_2 = 1$, so $d=\vert1-(-4)\vert$.

Step3: Simplify the expression

$\vert1-(-4)\vert=\vert1 + 4\vert=\vert5\vert = 5$.

Answer:

C. 5 units
