If $-3$ and 5 are the coordinates of two points on the real number line, the distance between these points is _________.

The distance between the given points is 8.

The given statement is:

If and 5 are the coordinates of two points on the real number line, the distance between these points is _________.

Subtract the smaller number from the larger number.

$\begin{array}{rcl}5-(-3)& =& 5+3\\ & =& 8\end{array}$

We can use absolute value to calculate the distance between two points without being concerned about which is smaller.

$\begin{array}{rcl}\left|-3-5\right|& =& \left|-8\right|\\ & =& 8\end{array}$

The distance between the given points is 8.
