The abscissa of a point is its distance from the

Options

A. origin
B. x-axis
C. y-axis
D. none of these

Answer

To solve the question, "The abscissa of a point is its distance from the ___," we need to understand the concept of abscissa in coordinate geometry.

### Step-by-step Solution:

1. **Understanding Abscissa**:
- In a coordinate system, a point is represented by two numbers (x, y).
- The first number (x) is called the abscissa, and it represents the horizontal distance from the y-axis.

2. **Identifying the Axes**:
- The x-axis is the horizontal line on the graph, while the y-axis is the vertical line.
- The abscissa indicates how far the point is from the y-axis.

3. **Distance Measurement**:
- The distance of the abscissa is measured along the x-axis, starting from the y-axis.
- Therefore, the abscissa is the horizontal distance from the y-axis.

4. **Choosing the Correct Option**:
- Based on our understanding, the abscissa of a point is its distance from the y-axis.
- If the options provided include "y-axis," that would be the correct answer.

### Final Answer:
The abscissa of a point is its distance from the **y-axis**.
