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

1. x-coordinate = -5

2. y-coordinate = 5 only

3. y-coordinate = -5 only

4. y-coordinate = 5 or -5

In graph, let 1 block = 1 unit.

Since,

Perpendicular distance of a point P from the x-axis is 5 units and the foot of perpendicular lies on the negative direction of x-axis.

Let foot of perpendicular be B.

So, position of point P can be A or C.

From graph,

The y-coordinate of A and C = 5 and -5.

Hence, Option 4 is the correct option.
