Question

If the perpendicular distance of a point $P$ from the $X$-axis is $5$ units and the foot of the perpendicular lies on the negative direction of $X$-axis, then the point $P$ has

• A. $X$-coordinate $=-5$
• B. $Y$-coordinate $=-5$
• C. $Y$-coordinate $=-5$ only
• D. $Y$-coordinate $=5$ or $-5$

Answer 1

Answer: (D)

$Y$-coordinate $=5$ or $-5$

Perpendicular distance from $X$-axis gives the ordinate and here the ordinate can be positive or negative as the distance will be $+$ve regardless.

So, option $D$ is correct.
