Remember that


... Start with the given equation.


... Plug in


... Take the tangent of both sides.


... Evaluate the tangent of 45 degrees to get 1.


... Evaluate the tangent of the arctangent of y%2Fx to get y%2Fx. In other words, the two cancel out.


... Multiply both sides by x.


So the rectangular equation is y=x.
