Question

find the distance between c and d on the number line below.

Explanation:

Step1: Identify coordinates

The coordinate of C is - 11 and the coordinate of D is - 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, let $x_1=-11$ and $x_2 = - 1$. Then $d=\vert-1-(-11)\vert$.

Step3: Simplify the expression

$\vert-1-(-11)\vert=\vert-1 + 11\vert=\vert10\vert = 10$.

Answer:

10
