Given below are the Class 9 Maths Important Questions for Coordinate Geometry
a) Concepts questions1. State the quadrant for each of these points in Cartesian plane
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
