Question

What is the perpendicular distance of the point (x, y) from x-axis ?

• A. x
• B. y
• C. |x|
• D. |y|

Answer 1

The correct option is D |y|

The perpendicular distance from $y$-axis to a point $(x,y)$ is $x$-coordinate

So, $|x|$ is the distance.

Similarly, the perpendicular distance from $x$-axis to a point $(x,y)$ is $y$-coordinate

So, $|y|$ is the distance.

We use absolute value as the coordinates may be negative and distance should be positive.

Hence, D is correct.
