Answer 3

where is 1 on the number line?

Answer 4

There is no image. Just use the one that I attached.

Answer 5

I'm asking you to try to fine where 1 is on the number line yourself

Answer 6

It's really confusing. It says -(-1) and that's really confusing.

Answer 7

negative means 'on the other side of 0'
so if 1 is on the right side of 0
then -1 is on the left side of 0

then the negative of -1
would make it go back to the right side of 0
therefore, -(-1) = 1
