Which whole number represents the y coordinate of any point lying on t

1.	Which whole number represents the y coordinate of any point lying on the x axis?
Answer» 0If a\xa0point lies on the x-axis\xa0then its\xa0y-coordinate\xa0is 0. Similarly, a\xa0point\xa0on the\xa0y-axis\xa0has its\xa0x-coordinate\xa00. The origin has\xa0coordinates\xa0(0,0). On the right you see an example of a (Cartesian)\xa0coordinate\xa0plane with some\xa0points\xa0sketched in it.
