What is the absolute value of -5?

-5
0
5
-1

The correct answer is: 5

The absolute value of a number is defined as the distance of that number from zero on the number line, regardless of direction. This means that absolute values are always non-negative. For the number -5, the absolute value focuses on the magnitude without considering its sign. Since -5 is 5 units away from zero, its absolute value is 5. Thus, the correct answer is indeed 5. The other options do not encapsulate this definition. -5 is negative and does not represent distance from zero, 0 indicates no distance, and -1 is also negative and does not pertain to the concept of absolute value in this context.
