Question

.
Explain how you could use a number line to determine the absolute value of −13
.

Answer 1

The absolute value of −13 is 13, since absolute value represents the distance a number is from zero, regardless of whether it is positive or negative.

To use a number line to determine the absolute value of −13, you would start at zero on the number line and count 13 spaces to the left, as negative numbers are found to the left of zero on a number line. The 13th space you land on is the number that has an absolute value of 13, which is positive 13.
