Find the 3 × 3 matrix that produces the described composite 2D transformation, using homogeneous coordinates.
-Translate by (8, 6) , and then reflect through the line y = x.

A)
$\left[\begin{array}{rrr}-1 & 0 & -8 \\0 & -1 & -6 \\0 & 0 & 1\end{array}\right]$

B)
$\left[\begin{array}{lll}0 & 1 & 8 \\1 & 0 & 6 \\0 & 0 & 1\end{array}\right]$

C)
$\left[\begin{array}{lll}0 & 6 & 1 \\8 & 0 & 0 \\0 & 0 & 1\end{array}\right]$

D)
$\left[ \begin{array} { l l l } 0 & 1 & 6 \\ 1 & 0 & 8 \\ 0 & 0 & 1 \end{array} \right]$
