system
In the rectangular coordinate system $(xOy)$, the parametric equations of line $l$ are given by $\begin{cases} x = -2 + t\\ y = -2t \end{cases}$ (where $t$ is the parameter), and the standard equation of circle $C$ is $x^2 + y^2 - 2y = 0$. Establish a polar coordinate system with $O$ as the pole and the positive half of the $x$-axis as the polar axis.
(1) Find the polar equation of line $l$;
(2) Let $M(ρ, θ)$ (where $ρ ≥ 0, 0 ≤ θ < 2π$) be a moving point on line $l$, and let $MA$ be the tangent line to circle $C$ at point $A$. Find the minimum value of $|MA|$ and the polar coordinates of point $M$ in this case.
