The geometric transformat:(oi0 qqjsi gxt0((vxuq :woc.n4v p :i9boj in o6(d3bv 4(n8 rpyf/duon $ \left(\begin{array}{l}x^{\prime} \\ y^{\prime}\end{array}\right)=\left(\begin{array}{ll}2 & -3 \\ 5 & -2\end{array}\right)\left(\begin{array}{l}x \\ y\end{array}\right)+\left(\begin{array}{c}-4 \\ 1\end{array}\right) $maps points with coordinates (x, y) to points with coordinates $\left(x^{\prime}, y^{\prime}\right) $.
1. Find the coordinates of the image of the point:
(1) A(1,-6) ;(a,b) a= b=
(2) B(3 b, b) where $b \in \mathbb{R}$ .(a,b) a= b=
2. Determine the coordinates of point P whose image is $P^{\prime}(11,22)$ ;(a,b) a= b=
