Question

What is the value of the y coordinate of any point on the x axis?

Answer 1

The value of the y coordinate of any point on the x axis is always 0.

Explanation

Suppose, the co ordinate of any point is $(a,b)$ .

It means, the distance of the point from x-axis is '$b$' and distance from y-axis is '$a$'.

Now if the point lies on the x-axis, that means the distance of the point from x-axis will be 0. Thus, the value of '$b$' will be 0.

So, the value of the y coordinate of any point on the x axis is always 0.
