Multiple Choice

Find the inverse matrix of A.
- $$A = \left[ \begin{array} { r r } - 1 & 3 \\0 & - 2\end{array} \right]$$

A) $\left[ \begin{array} { r r } - \frac { 1 } { 2 } & - \frac { 3 } { 2 } \\ 0 & - 1 \end{array} \right]$
B) $\left[ \begin{array} { r r } - 1 & - \frac { 3 } { 2 } \\ 0 & - \frac { 1 } { 2 } \end{array} \right]$
C) $\left[ \begin{array} { r r } - 1 & \frac { 3 } { 2 } \\ 0 & - \frac { 1 } { 2 } \end{array} \right]$
D) $\left[ \begin{array} { r r } 0 & - \frac { 1 } { 2 } \\ - 1 & - \frac { 3 } { 2 } \end{array} \right]$
