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