Question

On which axis do the following points lie?

(i) $P(5,0)$ (ii) $Q(0.-2)$ (iii) $R(-4,0)$ (iv) $S(0,5)$

Answer 1

If the point lies on the x-axis, y co-ordinate =0

If the point lies on the y-axis, x co-ordinate =0

$P(5,0)$ y co-ordinate=0, so the point lies on x-axis

$Q(0,-2)$ x co-ordinate=0, so the point lies on y-axis

$R(-4,0)$ y co-ordinate=0, so the point lies on x-axis

$S(0,5)$ x co-ordinate=0, so the point lies on y-axis
