The distance of a point $P(3,-7)$ from y-axis is :

Question

Accepted Answer

Step 1: The perpendicular distance of a point $(x,y)$ from the y-axis equals $|x|$.
Step 2: Here $P(3,-7)$, so $x=3$.
Step 3: Distance $=|3|=3$ units.
(Note: the distance from the x-axis would be $|-7|=7$ units.)
Correct option is (A) 3.
