**Diagram Explanation:**

- The diagram shows a number line labeled "x (m)" with marks from -4 to 4.
- A 7.50 kg mass is represented by an orange circle placed at -2.00 m.
- A 1.15 kg mass is represented by a green circle placed at 4.00 m.

**Answer Choices:**

- ○ 2.26 m
- ○ 1.00 m
- ● 1.20 m
- ○ -1.20 m
- ○ 6.00 m

The correct answer is **1.20 m**.
