Question

Which of the following points lies on the x-axis
(i) $(1,1)$
(ii) $(1,0)$
(iii)$(0,1)$
(iv)$(0,0)$
(V)$(-1,0)$
(vi)$(0,-1)$
(vii)$(4,0)$
(viii)$(0,-7)$

Answer 1

Points of the form $(a,0)$, i.e. the points in which y - coordinate is 0, lie on the x-axis.
Hence, the points $(1,0),(0,0),(-1,0),(4,0)$ lie on the x-axis.
