Question 1. From the following figure write:
(i) the points whose abscissa is 0.
(ii) the points whose ordinate is 0.
(iii) the points whose abscissa is –5
In an ordered pair (x, y), the first entry ‘x’ is the abscissa and the second entry ‘y’ is the ordinate of the point. Let us prepare the following table of ordered pairs of the given points. Also let us write their respective abscissa and ordinate.
From the table we get:
(i) Points with abscissa = 0 are A, L, and O.
(ii) Points with ordinate = 0 are G, I, and O.
(iii) Points with abscissa = –5 are D, H.
The Point  Ordered pair  Abscissa  Ordinate 
A  (0, 3)  0  3 
B  (4, 4)  4  4 
C  (3, 3)  3  3 
D  (5, 1)  5  1 
E  (2, 1)  2  1 
F  (2, 1)  2  1 
G  (5, 0)  5  0 
H  (5, 3)  5  3 
I  (2, 0)  2  0 
J  (6, 4)  6  4 
K  (2, 5)  2  5 
L  (0, 4)  0  4 
M  (4, 3)  4  3 
N  (3, 5)  3  5 
P  (3, 5)  3  5 
O  (0, 0)  0  0
