Question

what is the y coordinate of every point on x-axis? ​

Answer 1

Answer:

We know that the y−coordinates of every point on x−axis are zero. So, the coordinates of any point on thex−axis are of the form (x,0) .

Answer 2

Answer:

Any point on x axis has coordinates as (a,0) where a>0, a<0 or a=0. Similarly any point on y axis has coordinates (0,b) where b>0, b<0 or b=0. Hope this works…. X-axis and Y-axis both are infinitely long straight lines. So they don't have constant coordinates (as coordinate defines a fixed point..
