Answer: ax + by + cz + d = 0.
- A ax + by + cz + d = 0
- B ax + by = 0
- C ax2 + by2 + cz2 = 0
- D x/a = y/b = z/c
Correct answer: A. ax + by + cz + d = 0
Explanation: The general equation of a plane in 3D is ax + by + cz + d = 0, where (a,b,c) is the normal vector to the plane.
Three mutually perpendicular axes x, y, z meeting at the origin O, with a point P located by its (x, y, z) coordinates.
