Class 9 Maths Important Questions for Coordinate Geometry

Given below are the Class 9 Maths Important Questions for Coordinate Geometry
a) Concepts questions
b) Calculation problems
c) Multiple choice questions
d) Long answer questions
e) Fill in the blank's
  1. State the quadrant for each of these points in Cartesian plane

1. (2,3)
2. (3,-9)
3. (-9,-8)
4. (1,1)
5. (-2,7)
6. (2,0)
7. (0,3)

Solution
We know the quadrant signs are given below

Quadrant	x-coordinate	y-coordinate
Ist Quadrant	+	+
IInd quadrant	-	+
IIIrd quadrant	-	-
IVth quadrant	+	-

So we can easily find the quadrant for each of these points
2. Plot the following points in the Cartesian plane
a)  (9, 8)
 b) (-1,-1)
c) (6, 6)
d) (4, 4)
Also find which of these three lie are collinear
3) True or False statement
a) x –coordinate is positive in Ist and  IIIrd quadrants
b) The (0,0) is the coordinate of origin
c) The point ( 0,2) lies on y axis
d) The ordinate of the point Q ( 2,3) is 2
e) Abscissa of all points on y axis is zero
f) The points P ( 2,3) and Q ( -3,2) lie in the same quadrant
Solution

1. False ,x-axis is positive in I and IV quadrant
2. True
3. True
4. false
5. True
6. False

Multiple choice Questions
4) The perpendicular distance of the point X ( 5,6) from X axis is
a) 5
b) 6
c) 4
d) 1
Solution (b)
5. The perpendicular distance of the point X ( 2,3) from Y axis is?
a)  2
b) 3
c)  5
d) None of these
Solution (a)
6) The points ( other than origin ) whose abscissa and ordinates are same will lie in
a) I and III quadrants
b)II and III quadrants
c) II quadrants only
d) none of these
Solution (a)
7)  The positive abscissa lies in which quadrants
a) I
b) II
c) III
d) IV
Solution (a), (d)
8) Ordinate of all the points on x-axis is
a) 0
b) 1
c) 2
d) Any number
Solution (a)
