Chapter 1.1, Problem 2AYU

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

To determine

To find: The distance between the two points $-3$ and 5 on the real number line.

Answer to Problem 2AYU

8

Explanation of Solution

Given:

The coordinates of the two points on the number line are $\text{A}\left(-3,\mathrm{ 0}\right)$ and $\text{B}(5,0)$

Calculation:

Distance $=5-\left(-3\right)$

$=5+3$

$=8$

Thus the distance between the two points whose coordinates are $-3$ and 5 is 8.
