The abscissa of a point is positive in the First and Second quadrant (b) Second and Third quadrant Third and Fourth quadrant (d) Fourth and First quadrant

Options

A. I and II quadrants
B. I and IV quadrants
C. I quadrant
D. II quadrant

Explanation

To determine in which quadrants the abscissa (x-coordinate) of a point is positive, we can analyze the four quadrants of the Cartesian plane.

### Step-by-Step Solution:

1. **Understand the Definition of Abscissa**:
- The abscissa refers to the x-coordinate of a point in the Cartesian coordinate system.

2. **Identify the Quadrants**:
- The Cartesian plane is divided into four quadrants:
- **First Quadrant (I)**: Both x and y coordinates are positive (x > 0, y > 0).
- **Second Quadrant (II)**: The x coordinate is negative and the y coordinate is positive (x < 0, y > 0).
- **Third Quadrant (III)**: Both x and y coordinates are negative (x < 0, y < 0).
- **Fourth Quadrant (IV)**: The x coordinate is positive and the y coordinate is negative (x > 0, y < 0).

3. **Determine Where the Abscissa is Positive**:
- From the definitions:
- In the **First Quadrant**, the abscissa (x) is positive.
- In the **Fourth Quadrant**, the abscissa (x) is also positive.
- In the **Second Quadrant**, the abscissa is negative.
- In the **Third Quadrant**, the abscissa is negative.

4. **Conclusion**:
- The abscissa of a point is positive in the **First Quadrant** and the **Fourth Quadrant**.

5. **Select the Correct Option**:
- Based on the analysis, the correct answer is that the abscissa is positive in the **First and Fourth Quadrants**.

### Final Answer:
The abscissa of a point is positive in the **First and Fourth Quadrants**.
