Question

A point is plotted on the number line at 3. A second point is plotted at 5.

What is the length of a line segment joining these points?
Enter your answer as a simplified mixed number in the box.
PLEASE HELP!!

Answer 1

`\huge{\boxed{2 \text{ units}}}`

Explanation:

N.B. I attached an image of the number line as presented by the problem.

The absolute value of a number is its distance from zero. A simple way to say that is that the absolute value of a number is the number made positive and is denoted by "||"

i.e.

|-4| = 4

|4| = 4

|-219| = 219

The distance between two points on a number line is the absolute value of their difference. Thus, simply do:

|5 - 3|

|2|

2

OR

|3 - 5|

|-2|

2

Thus, the length of the segment is simply 2.

Hope it helps :) and let me know if you want me to elaborate.
