Question

Find the equation of a plane that passes through and is perpendicular to

Answer 1

In order to use this formula, a point in the plane and a vector perpendicular to the plane are needed. A vector perpendicular to the plane is called a normal to the plane. Example: Find an equation for the plane that passes through thegiven points P1(-2,1,1), P2(0,2,3), and P3(1,0,-1).
