Chapter 3 MATHS : Co-ordinate Geometry — Important Questions & Answers
What is the point of intersection of the x-axis and y-axis called?
- A. Quadrant
- B. Origin
- C. Axis
- D. Coordinates
Answer: B. Origin
The x-axis and y-axis intersect at the origin. Its coordinates are (0, 0).
The x-axis and y-axis intersect at the origin. Its coordinates are (0, 0).
How many quadrants are there in the Cartesian plane?
- A. 2
- B. 3
- C. 4
- D. 8
Answer: C. 4
The Cartesian plane is divided by the x-axis and y-axis into four regions called quadrants.
The Cartesian plane is divided by the x-axis and y-axis into four regions called quadrants.
If a point has coordinates (5, -2), in which quadrant does it lie?
- A. Quadrant I
- B. Quadrant II
- C. Quadrant III
- D. Quadrant IV
Answer: D. Quadrant IV
In Quadrant IV, the x-coordinate is positive and the y-coordinate is negative. The point (5, -2) fits this rule.
In Quadrant IV, the x-coordinate is positive and the y-coordinate is negative. The point (5, -2) fits this rule.
A point is 3 units to the left of the y-axis and 2 units above the x-axis. What are its coordinates?
- A. (3, 2)
- B. (-3, 2)
- C. (-3, -2)
- D. (3, -2)
Answer: B. (-3, 2)
Left of the y-axis means x is negative, and above the x-axis means y is positive. So the point is (-3, 2).
Left of the y-axis means x is negative, and above the x-axis means y is positive. So the point is (-3, 2).
Which of the following points does NOT lie on either axis?
- A. (0, 4)
- B. (-6, 0)
- C. (0, 0)
- D. (3, -2)
Answer: D. (3, -2)
A point lies on an axis if either x = 0 or y = 0. The point (3, -2) has neither coordinate equal to 0, so it lies on neither axis.
A point lies on an axis if either x = 0 or y = 0. The point (3, -2) has neither coordinate equal to 0, so it lies on neither axis.
