7 The matrix \(\left( \begin{array} { l l } 1 & 3
0 & 1 \end{array} \right)\) represents a transformation P .
- Describe fully the transformation P .
The matrix \(\mathbf { M }\) is given by \(\mathbf { M } = \left( \begin{array} { r r } - 3 & - 1
- 1 & 0 \end{array} \right)\). - Given that \(\mathbf { M }\) represents transformation Q followed by transformation P , find the matrix that represents the transformation Q and describe fully the transformation Q .
