Answer:
The equation of the plane is represented by
.
Step-by-step explanation:
Algebraically speaking, a plane can be represented by following vectorial product:
(1)
Where:
,
,
- Plane coeffcients.
,
,
- Coordinates.
We need three distinct points to determine all coefficients. If we know that
,
and
, the system of equations to be solved is:
(1)
(2)
(3)
The solution of this system is
,
,
.
Hence, the equation of the plane is represented by
.
