Adjacent figure is a vertical number line, representing integers. Observe it and locate the following points : (a) If point D is `+8` , then which point is `−8` ? (b) Is point G a negative integer or a positive integer? (c) Write integers for points B and E. (d) Which point marked on this number line has the least value? (e) Arrange all the points in decreasing order of value.

Explanation

To solve the problem step by step, we will analyze the vertical number line representing integers and answer each part of the question accordingly.

### Step-by-Step Solution:

1. **Identify Point D and Find Point F**:
- Given that point D is `+8`, we need to locate `-8` on the number line.
- On the vertical number line, the negative counterpart of `+8` is `-8`, which corresponds to point F.
- **Answer**: Point F is `-8`.
