How do you represent a plane?

A plane can be represented in three-dimensional space using a linear equation of the form (Ax + By + Cz + D = 0), where (A), (B), and (C) are the coefficients that define the normal vector to the plane, and (D) is a constant. Alternatively, a plane can be described parametrically using a point on the plane and two non-parallel direction vectors that lie within the plane. This allows for a more visual representation and is useful in various applications, such as computer graphics and physics.
