Answer:
≠ (not equal)
Step-by-step explanation:
Out of the three choices provided, it has to be the not equal sign. We know this because the absolute value of 1 is how far away 1 is from 0, which is 1. Which then makes our equation: 1 ____ -1.
From here, it's easy to tell that -1 is smaller than 1, they're not equal, and it is possible. Since we have eliminated all other possible answers, we know it has to be ≠.
