coordinate geometry class 9 extra questions

Question 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

So we can easily find the quadrant for each of these points

Question 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
Solution

Question 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

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

Question 4
Fill in the blanks (a) The point at which the two coordinate axes meet is called the _____
(b) The point (-10,-11) lies in ____quadrant

(f) distance between the points (2, 0) and (-2, 0) is _____
Solution
1. Origin
2. Third
3. 12
4. 2
5. x=y
6. 4
