The point (1, –2), (2, –3), (4, –6), (2,–7) lies in:
Mastering Coordinate Geometry is essential for students as it connects algebra with geometry. In Class 9th Mathematics Chapter 3 students learn about the Cartesian plane plotting points and measuring distances. NCERT solutions provide clear step-by-step explanations making problem-solving easier. MCQ-based questions test understanding while short-answer questions aid in quick revision. This chapter builds logical reasoning skills and strengthens the foundation for higher studies. Regular practice of exercise questions ensures better exam preparation and real-world application. With structured solutions students can grasp concepts effectively and develop confidence in mathematics.

Determining the Quadrant of Given Points
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)
Analyzing Each Point
1. Point (1 , -2)
x = 1 (positive), y = -2 (negative). Lies in Quadrant IV
2. Point (2, -3)
x = 2 (positive), y = -3 (negative). Lies in Quadrant IV
3. Point (4, -6)
x = 4 (positive), y = -6(negative). Lies in Quadrant IV
4. Point (2, -7)
x = 2 (positive), y = -7 (negative). Lies in Quadrant IV
Conclusion: All four points lie in Quadrant IV.
Final Answer: (c) IV quadrant.
