Question

If the perpendicular distance of a point P from the x-axis is 5 unit then the point P has ______.

Options

• x-co-ordinate = −5

• y-co-ordinate = 5 only

• у-cо-ordinate = −5 only

• x-co-ordinate = 5 or −5

Answer 1

If the perpendicular distance of a point P from the x-axis is 5 unit then the point P has x-coordinate = 5 or −5.

Explanation:

The perpendicular distance of a point from the x-axis is equal to the absolute value of its y-coordinate (|y|). Since the perpendicular distance from the x-axis is given as 5 units, the y-coordinate can be either 5 or −5 (depending on whether the point lies above or below the x-axis).
