Answer: y = 0, z = 0.
- A y = 0, z = 0
- B x = 0, z = 0
- C x = 0, y = 0
- D y = z = x = 0
Correct answer: A. y = 0, z = 0
Explanation: The x-axis is defined by y = 0 and z = 0. Any point on the x-axis has coordinates (x, 0, 0).
Three mutually perpendicular axes x, y, z meeting at the origin O, with a point P located by its (x, y, z) coordinates.
