(ii) A point whose y coordinate is zero and x-coordinate is 5 will lie on
y-axis.

(ii) False.Point  does not lie on y-axis.A point whose y coordinate is zero and x-coordinate is 5 will not lie on y-axis.

Q.4 State whether True or False. Correct that are false.
(i) A point whose x coordinate is zero and y-coordinate is non-zero will
lie on the y-axis.
