Question

The coordinates of the point P are given by (2,-4,5). Then,

• A. Distance of point P from the XY plane = 5
• B. Distance of point P from the XZ plane = $\sqrt{29}$
  
• C. Distance of point P from the YZ plane = 2
  
• D. Distance of point P from the XZ plane = 4

Answer 1

Answer: (A), (C), (D)

The correct options are
A Distance of point P from the XY plane = 5
C Distance of point P from the YZ plane = 2

D Distance of point P from the XZ plane = 4

The perpendicular distance from the XZ plane is given by the modulus of the Y-coordinate, the perpendicular distance from the YZ plane is given by the modulus of the X-coordinate and the perpendicular distance from the XY plane will given by the modulus of the Z-coordinate.
So, the distance from the XY plane = 5
The distance from the YZ plane = 2
The distance from the XZ plane = 4
