A triangle with vertices A
u *b(0iu ir.io(6,6), B(3,1) and C(1,3) is transformed by x′=Ax+b
where A = $\begin{pmatrix}
-1&2 \\
-2&1
\end{pmatrix}$and b = $\begin{pmatrix}
-6 \\
3
\end{pmatrix}$.
1.On the following grid, draw the image of the triangle ABC.
2.Given the area of the triangle ABC is 16 $units^2$, find the area of its image.
$units^2$
