Chapter-5 Coordinate Geometry — Online MCQ Test

Q: What is the name of the point where the x-axis and y-axis intersect?

Answer: B. Origin — The x-axis and y-axis intersect at the origin, whose coordinates are (0, 0).

Q: Which of the following represents the coordinates of a point in the Cartesian plane?

Answer: A. (x, y) — A point in the Cartesian plane is written as an ordered pair in the form (x, y).

Q: What are the coordinates of the point that lies on the y-axis and is 5 units above the origin?

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).

Q: Which of the following is NOT a quadrant in the Cartesian plane?

Answer: C. Quadrant V — The Cartesian plane has only four quadrants: I, II, III, and IV. Quadrant V does not exist.

Q: 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?

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.
