Question

On which axis do the following points lie?
(i) (7, 0)
(ii) (0, −5)
(iii) (0, 1)
(iv) (−, 0)

Answer 1

(i) In (7,0), ordinate = 0
∴ (7,0) lies on the x-axis.

(ii) In (0,-5), abscissa = 0
∴ (0,-5) lies on the y-axis.

(iii) In (0,1), abscissa = 0
∴ (0,1) lies on the y-axis.

(iv) In (-4,0), ordinate = 0
∴ (-4,0) lies on the x-axis.
