## Rectangle to Polar Form

How would I change: 2x+3y=4
into polar form? I understand how to solve for polar form but the 4 without a variable is confusing me.

 $$2 r cos \theta + 3 r sin \theta = 4$$ $$r(2 cos \theta + 3 sin \theta) = 4$$ $$2 cos \theta + 3 sin \theta = 4/r$$ $$\frac{4}{2 cos \theta + 3 sin \theta} = r$$ whats wrong with that?
 Thank you I feel ashamed that such a simple problem stumped me. I was thinking to hard lol. Thanks again
