Question:

From P(-3,2), the foot of a perpendicular drawn on the Y-axis is M. The coordinates of M are?

(-3,2)

(3,0)

(0,2)

(32,1)

Solution:

The correct option is B (0,2)
From P(-3,2), If the foot of perpendicular is drawn from point (x1,y1) on the y-axis, then x-coordinate of the point drawn will be x1=0.
∴ x-co-ordinate of the foot of the perpendicular to the y-axis is 0 and y-coordinate = 2
∴ Coordinates of M = (0,2)
