e) Fill in the blank's
1. State the quadrant for each of these points in Cartesian plane
- (2,3)
- (3,-9)
- (-9,-8)
- (1,1)
- (-2,7)
- (2,0)
- (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
- False ,x-axis is positive in I and IV quadrant
- True
- True
- false
- True
- False
