Answer:

AC = 9 units

Explanation:

The length of something can never be negative. 0 means it doesn't exist, but negative is impossible. By counting the number of tick marks along the line you can find how long AC is. You can also use addition to help you:

4 + 5 = 9

When adding the length of something, ignore negative signs.
