The abscissa of any point on y-axis is (...

The abscissa of any point on y-axis is (a) 0 (b) 1 (c) `-1` (d) any number

Text Solution

Verified by Experts

We know that the x−coordinate of every point on y-axis is zero. So, the coordinates of any point on the x−axis are of the form `(0,y)`
Thus the correct answer is (a).
