Find the rule that translates quadrilateral \(ABCD\) to quadrilateral \(A'B'C'D'\).

\(\triangle A'B'C'\) is translated to \( \triangle A'' B'' C'' \) by the rule \((x ,\; y) \longrightarrow (x\; -\; 4 ,\; y\; +\; 3)\).

Find the coordinates of \(A'' ,\; B''\) and \(C''\), given

\(A(-3 ,\; 6) ,\; B(-1 ,\; 2),\; C(8 ,\; 2)\)
