In this video I start off with the linear equation of a plane and go backwards to show that, if at least one of a, b, and c are not zero, then the equation does indeed represent a plane. I show this by first assuming a is not equal to zero and writing the d term as (a d/a). Then I rewrite the equation as a dot product and simplify it further to show that it is just the vector equation of a plane. This is a good exercise and checkup on our earlier derivation of the linear equation of a plane.
