Answer 1

To determine the order of a matrix, we look at the number of rows and columns it has.

From your description, the matrix is presented as follows:

\[ \begin{bmatrix} -6 & -4 \ -4 & 1 \ -7 & -5 \end{bmatrix} \]

Let's count the rows and columns:

• Rows: There are 3 rows.
• Columns: There are 2 columns.

Therefore, the order of this matrix is 3 x 2 (3 rows and 2 columns).
