Solve for m (complex solution)
\left\{\begin{matrix}m=-\frac{c-y}{x}\text{, }&x\neq 0\\m\in \mathrm{C}\text{, }&y=c\text{ and }x=0\end{matrix}\right.
Solve for c
c=y-mx
Solve for m
\left\{\begin{matrix}m=-\frac{c-y}{x}\text{, }&x\neq 0\\m\in \mathrm{R}\text{, }&y=c\text{ and }x=0\end{matrix}\right.

mx+c=y
Swap sides so that all variable terms are on the left hand side.
mx=y-c
Subtract c from both sides.
xm=y-c
The equation is in standard form.
\frac{xm}{x}=\frac{y-c}{x}
Divide both sides by x.
m=\frac{y-c}{x}
Dividing by x undoes the multiplication by x.
mx+c=y
