Question

The equation of $x-axis$ is of the form

• A. $x=0$
• B. $y=0$
• C. $x+y=0$
• D. $x=y$

Answer 1

The correct option is B

$y=0$

The points on the x-axis are of the form $(a,0),$ where $a$ is any real number.

The $y-$coordinate of the point of the$x-axis$ is $0.$

The$x-axis$ is represented by the equation $y=0$

The equation of $x-axis$ is $y=0$

Hence, option (B) is correct.
