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

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 .

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

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 '' will be 0.

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

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
