If abscissa of a point is zero then that point will lie

Options

A. on x-axis
B. on y-axis
C. at origin
D. in 1st quadrant

Answer

To determine where a point lies when its abscissa (x-coordinate) is zero, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Abscissa and Ordinate**:
- The abscissa of a point is its x-coordinate, and the ordinate is its y-coordinate.
- A point in a 2D coordinate system is represented as (x, y).

2. **Given Condition**:
- The problem states that the abscissa of the point is 0. This means that the x-coordinate is 0.

3. **Identifying the Position**:
- If the x-coordinate (abscissa) is 0, the point can be represented as (0, y), where y can be any real number.

4. **Locating the Point**:
- When x = 0, the point lies directly on the y-axis.
- The y-axis is the vertical line where all points have an x-coordinate of 0.

5. **Conclusion**:
- Therefore, if the abscissa of a point is 0, that point will always lie on the y-axis.

### Final Answer:
If the abscissa of a point is zero, then that point will lie on the y-axis.
