Question

If the perpendicular distance of a point $P$ in a plane from $x$-axis is $2$ units and from $y$-axis is $7$ units, then its abscissa is:

• A. $0$
• B. $2$
• C. $7$
• D. None of the above

Answer 1

The correct option is C $7$

We know, in the $xy$-plane, any point is of the form $(x,y)$, where $x,y$ can be any non-zero number.

Here, the $x$-coordinate or the abscissa is the perpendicular distance of the point from the $y$-axis.

Also, the $y$-coordinate or the ordinate is the perpendicular distance of the point from the $x$-axis.

Here, the perpendicular distance of the point from $x$-axis is $2$ units and from $y$-axis is $7$ units.

Hence, the abscissa is $7$.

Therefore, option $C$ is correct.
