Given the polar equation of a line is $$ρ\sin(θ+ \frac {π}{4})= \frac { \sqrt {2}}{2}$$, and the parametric equation of circle M is $$\begin{cases} x=2\cosθ \\ y=-2+2\sinθ\end{cases}$$ (where θ is the parameter).
(Ⅰ) Convert the polar equation of the line into a Cartesian coordinate equation;
(Ⅱ) Find the minimum distance from a point on circle M to the line.
