<reasoning>
Count the rows of the matrix
Using the Matrix Dimensions knowledge point
\[
\text{Rows} = 2
\]
Count the columns of the matrix
Using the Matrix Dimensions knowledge point
\[
\text{Columns} = 3
\]
Determine the order of the matrix
Using the Matrix Dimensions knowledge point
\[
\text{Order} = \text{Rows} \times \text{Columns} = 2 \times 3
\]
