CBSE Class 9 Coordinate Geometry MCQ Table
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 the 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 the 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
11) Signs of the abscissa and ordinate of a point in the second quadrant are respectively
a. +, +
b. +, –
c. -, +
d. -, –
Answer: c
Explanation: The signs of abscissa (x-value) and ordinate(y-value) in the second quadrant are – and + respectively.
12) The point (-10, 0) lies in
a. Third quadrant
b. Fourth quadrant
c. On the negative direction of the x-axis
d. On the negative direction of the y-axis
Answer: c
Explanation: The lies (-10, 0) lies in the negative direction of the x-axis.
13) A quadrant in which both x and y values are negative is
a. First quadrant
b. Second quadrant
c. Third quadrant
d. Fourth quadrant
Answer: c
Explanation: In the third quadrant, both the abscissa and ordinate values are negative. Example (-2, -2), which lies in the third quadrant.
14) Abscissa of all the points on the x-axis is
a. 0
b. 1
c. 2
d. Any number
Answer: d
Explanation: Abscissa of all the points on the x-axis can be any number. The coordinates of any point on the x-axis is (x, 0), where x can take any value.
15) Ordinate of all points on the x-axis is
a. -1
b. 0
c. 1
d. Any number
Answer: b
Explanation: The ordinate of all points on the x-axis is 0. We know that the coordinates of any point on the x-axis is (x, 0). Here, the abscissa can take any value and the ordinate is zero.
