From other source on the internet this question is:

Which absolute value expression represents the distance between 3 and - 2 on a number line?

Answer:

|3 - (-2) |, or |-2 - 3|

Both are equivalent.

Explanation:

The distance between two numbers in a number line is the absolute value of the difference between the two numbers.

Thus, the distance between a number x and a number y is |x - y|, which is also equivalent to |y - x|.

In this case the distance between 3 and - 2 can be represented by either of the expressions:

|3 - (-2) |, or |-2 - 3|

Note that when you simplify them you get the same value:

|3 - (-2) | = |3 + 2| = |5| = 5 |-2 - 3| = | - 5| = 5

The distance between 3 and

on a number line is |3 -
