Step-by-step explanation:
4. Each unlabelled opposites are positioned at a 0.5 interval. That means each division in between 0 and 1, 1 and 2, 2 and 3, 3 and 4 are 0.5. So we have 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4
Same idea is applicable on the negative side of the graph. We have 0, -0.5, -1, -1.5, -2, -2.5, -3, -3.5, 4.
5. Like 4 above, each unlabelled opposite is positioned at an 0.5 or 1/2 interval.
So we have, 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4 (for the positive side) and 0, -0.5, -1, -1.5, -2, -2.5, -3, -3.5, 4 (for the negative side).
6a.
A positive number is one greater than zero while a negative number is one lesser than zero. So we have -0.5 and 0.5
6b. -0.4, 0.4
6c. -3.5, -3 1/2
