6. Triangle \( C D E \) with vertices \( C(-2,-2), D(1,-4) \), and \( E(-3,-4) \) :
a) dilation with scale factor of 4 centered ( \( -1,-3 \) )
b) reflection in the line \( y=-x \)
\[
\begin{array}{l}
C^{\prime}(\square, \square) \\
D^{\prime}(\square, \square) \\
E^{\prime}(\square, \square)
\end{array}
\]
