    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

    Correct Answer: B

    Solution :

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