In how many directions can a line extended?

Answer

To solve the question "In how many directions can a line be extended?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding a Line**: A line is a straight path that extends infinitely in both directions. It does not have endpoints.
- **Hint**: Remember that a line is different from a line segment, which has two endpoints.

2. **Visualizing the Line**: Imagine a line drawn on a piece of paper. It goes on forever in both directions. You can think of it as a straight arrow that continues indefinitely.
- **Hint**: Visual aids can help you understand how a line looks compared to a line segment.

3. **Identifying Directions**: Since a line extends infinitely, we can consider the directions in which it can be extended. A line can be extended to the left and to the right.
- **Hint**: Think about the number of ways you can move along the line without stopping.

4. **Conclusion**: Therefore, a line can be extended in **two directions**: one direction to the left and one direction to the right.
- **Hint**: Remember that the concept of direction refers to the two opposite ways a line can go.

### Final Answer:
A line can be extended in **two directions**.
