Theorem
Formulation 1
Let $\C$ be the complex plane.
Let $L$ be a straight line in $\C$.
Then $L$ may be written as:
- $\beta z + \overline \beta \overline z + \gamma = 0$
where $\gamma$ is real and $\beta$ may be complex.
Formulation 2
Let $\C$ be the complex plane.
Let $L$ be the infinite straight line in $\C$ which is the locus of the equation:
- $l x + m y = 1$
Then $L$ may be written as:
- $\map \Re {a z} = 1$
where $a$ is the point in $\C$ defined as:
- $a = l - i m$
