Which number is farther from 0 on a number line -9 or 6?

-9 because:
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
this side is lower                    this side is higher
-=negative witch means its minus so -9 is lower

put like terms together.orremember that the 45 becomes negative when moved to the other side.orthe minuses cancel out.
