The abscissa of any point on the y-axis is _____________

Answer

To solve the question "The abscissa of any point on the y-axis is _____________", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Coordinates**:
- In a Cartesian coordinate system, every point is represented by an ordered pair (x, y), where 'x' is the abscissa (the x-coordinate) and 'y' is the ordinate (the y-coordinate).

2. **Identifying the Y-Axis**:
- The y-axis is the vertical line in the Cartesian plane where the x-coordinate (abscissa) of any point is measured.

3. **Analyzing Points on the Y-Axis**:
- Any point that lies on the y-axis has the form (0, y), where 'y' can be any real number. This means that the x-coordinate (abscissa) is always 0.

4. **Conclusion**:
- Therefore, the abscissa of any point on the y-axis is 0.

### Final Answer:
The abscissa of any point on the y-axis is **0**.
