Which is not equal to the absolute value of -1?
timurjin [86]

Answer:

-2

Step-by-step explanation:

Absolute value is the distance from a number to 0 on the number line, so the number can't be negative, only positive. The absolute value of -1 would be 1, therefore it couldn't be -2, or any other negative numbers.
