Answer: z = 0.
- A z = 0
- B x = 0
- C y = 0
- D x + y = 0
Correct answer: A. z = 0
Explanation: The XY-plane contains all points where z = 0. Similarly, the YZ-plane is x = 0 and XZ-plane is y = 0.
Three mutually perpendicular axes x, y, z meeting at the origin O, with a point P located by its (x, y, z) coordinates.
