Understanding the Sign of the X-Coordinate in the Third Quadrant
A point (x, y) lies in a specific quadrant based on the signs of its coordinates:
Quadrant I → (x > 0, y > 0)
Quadrant II → (x 0)
Quadrant III → (x < 0, y 0, y < 0)
For a Point in the Third Quadrant (III):
The x-coordinate is negative (x < 0).
The y-coordinate is also negative (y < 0).
Final Answer: (b) –
