Ineed with this i can't figure out.

That should be right, because the absolute value of -9 would be 9, but the negative sign in front makes it -9.

Your selected answer is correct because the absolute value of -9 is 9, and the negative sign outside the absolute number symbols makes it 9 negative, so -9=-9. BUT, we notice that there are choices for "greater than or equal to" and "less than or equal to". Those ones are correct too because it can be one or the other (greater than or equal to, less than or equal to).

Equal to, less than or equal to, greater than or equal to (Choices 3, 4, and 5)
