Question

if abscissa of a point is zero ,on which axis do the point lies.

Answer 1

abscissa = x
x=0
point lie on y axis

Answer 2

The answer is y axis.

The abscissa is the horizontal term of an ordered pair. Thus, if the abscissa of a point (x coordinate) of a point is zero, the point lies on the y axis. When the abscissa is 0, it means that it is at the origin. On the other hand, the abscissae on the right and left sides of the x axis have positive and negative values respectively.
