L is the foot of the perpendicular drawn from a point P (6, 7, 8) on the xy-plane. What are the coordinates of point L?(A) (6, 0, 0) (B) (6, 7, 0) (C) (6, 0, 8)(D) none of these

Answer»

Since L is the foot of perpendicular from P on the xy-plane, z-coordinate is zero in the xy-plane. Hence, coordinates of L are (6, 7, 0).
