Question

The point $(3,4)$ is at a distance of _________ from $y$-axis.

• A. $2$ units
• B. $3$ units
• C. $5$ units
• D. $1$ unit

Answer 1

The correct option is B $3$ units

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 point is $(3,4)$ and the abscissa is $3$.

Hence, the given point is at a distance of $3$ units from $y$-axis.

Therefore, option $B$ is correct.
