A point P lies on the x-axis and another point Q lies on the y-axis.
Write the ordinate of point P.

Answer

To solve the question, we need to understand the concepts of coordinates and the position of points on the Cartesian plane.

### Step-by-Step Solution:

1. **Identify the Coordinates of Point P**:
- Point P lies on the x-axis. In a Cartesian coordinate system, any point on the x-axis has a y-coordinate (ordinate) of 0.
- Therefore, the coordinates of point P can be represented as \( P(x, 0) \), where \( x \) can be any real number.

2. **Define the Ordinate**:
- The ordinate of a point is its y-coordinate. Since point P is on the x-axis, its y-coordinate is 0.

3. **Conclusion**:
- Thus, the ordinate of point P is 0.

### Final Answer:
The ordinate of point P is 0.
