MCQs on Class 9 Maths Coordinate Geometry
1) The name of the horizontal line in the cartesian plane which determines the position of a point is called:
a. Origin
b. X-axis
c. Y-axis
d. Quadrants
Answer: b
2) The name of the vertical line in the cartesian plane which determines the position of a point is called:
a. Origin
b. X-axis
c. Y-axis
d. Quadrants
Answer: c
3) The section formed by horizontal and vertical lines determining the position of the point in a cartesian plane is called:
a. Origin
b. X-axis
c. Y-axis
d. Quadrants
Answer: d
4) The point of intersection of horizontal and vertical lines determining the position of a point in a cartesian plane is called:
a. Origin
b. X-axis
c. Y-axis
d. Quadrants
Answer: a
5) If the coordinates of a point are (0, -4), then it lies in:
a. X-axis
b. Y-axis
c. At origin
d. Between x-axis and y-axis
Answer: b
Explanation: Since, x=0 and y=-4. Hence, the point will lie in negative y-axis 4 units far from the origin.
6) If the coordinates of a point are (3, 0), then it lies in:
a. X-axis
b. Y-axis
c. At origin
d. Between x-axis and y-axis
Answer: a
Explanation: Since, x = 3 and y = 0, therefore, the point will lie at positive x-axis 3 units far from the origin.
7) If the coordinates of a point are (-3, 4), then it lies in:
a. First quadrant
b. Second quadrant
c. Third quadrant
d. Fourth quadrant
Answer: b
Explanation: Since x = -3 and y = 4, then if we plot the point in a plane, it lies in the second quadrant.
8) If the coordinates of a point are (-3, -4), then it lies in:
a. First quadrant
b. Second quadrant
c. Third quadrant
d. Fourth quadrant
Answer: c
Explanation: Since, x = -3 and y = -4, then if we plot the point in a plane, it lies in the third quadrant.
9) Points (1, 2), (-2, -3), (2, -3);
a. First quadrant
b. Do not lie in the same quadrant
c. Third quadrant
d. Fourth quadrant
Answer: b
10) If x coordinate of a point is zero, then the point lies on:
a. First quadrant
b. Second quadrant
c. X-axis
d. Y-axis
Answer: d
