Explanation:

Factors to determine a plane:-

  1. Three non-collinear points determine a plane.
  2. A-line and a point not on the line determine a plane.
  3. Two intersecting lines determine a plane.
  4. Two parallel lines determine a plane.

∴ The equation of a plane lying in extraordinary form does not determine the plane.
