Answer 1

Equation of x-axis is y=0, it is a horizontal line.

Explanation:

We need to find the equation of the x- axis and type of line it represents (vertical or horizontal ).

On the x-axis, the value of y is always 0 and the value of x can be and real number. Since y is free from x and its value is 0, therefore the equation of x-axis is

`y=0`

Value of y remains same. So, it represents a horizontal line which intersects the y-axis at 0.

Therefore, equation of x-axis is y=0, it is a horizontal line.
