Chapter-5 Coordinate Geometry — Important Questions & Answers
What is the name of the point where the x-axis and y-axis intersect?
- A. Quadrant
- B. Origin
- C. Axis point
- D. Center point
Answer: B. Origin
The x-axis and y-axis intersect at the origin, whose coordinates are (0, 0).
The x-axis and y-axis intersect at the origin, whose coordinates are (0, 0).
Which of the following represents the coordinates of a point in the Cartesian plane?
- A. (x, y)
- B. [x, y]
- C. {x, y}
- D. x + y
Answer: A. (x, y)
A point in the Cartesian plane is written as an ordered pair in the form (x, y).
A point in the Cartesian plane is written as an ordered pair in the form (x, y).
What are the coordinates of the point that lies on the y-axis and is 5 units above the origin?
- A. (5, 0)
- B. (0, 5)
- C. (−5, 0)
- D. (0, −5)
Answer: B. (0, 5)
Any point on the y-axis has x-coordinate 0. Since it is 5 units above the origin, the coordinates are (0, 5).
Any point on the y-axis has x-coordinate 0. Since it is 5 units above the origin, the coordinates are (0, 5).
Which of the following is NOT a quadrant in the Cartesian plane?
- A. Quadrant I
- B. Quadrant II
- C. Quadrant V
- D. Quadrant IV
Answer: C. Quadrant V
The Cartesian plane has only four quadrants: I, II, III, and IV. Quadrant V does not exist.
The Cartesian plane has only four quadrants: I, II, III, and IV. Quadrant V does not exist.
The coordinates of a point are such that its x-coordinate is twice its y-coordinate, and the point lies on the line segment joining (0, 0) and (6, 3). Which point is it?
- A. (2, 1)
- B. (3, 1)
- C. (4, 2)
- D. (6, 3)
Answer: A. (2, 1)
A point on the line segment joining (0, 0) and (6, 3) with x = 2y must satisfy both conditions. (2, 1) lies on the segment and x = 2y.
