Question

State True or False:
The equation of the $x$-axis is $x=0$.

Answer 1

The equation of $x$-axis involves only $x$-axis. So, at that point $y$-axis does not exist in the picture and thus $y=0$.

But, as $x$-axis involves all the points of $x$-axis. So, $x\ne 0$.

Hence, the given statement is false.
