Given C(6, 10), D(2, 6), DA = 4 \ 4 and BC = 4 \ 4 , find the coordinates of B.

Step 1: Determine the coordinates of B and C.
From the problem description (9b(i)), we are given $C(6, 10)$ and $D(2, 6)$.
We are also given the vectors $\vec{DA} = \begin{pmatrix} 4 \\ 4 \end{pmatrix}$ and $\vec{BC} = \begin{pmatrix} 4 \\ 4 \end{pmatrix}$.
To find the coordinates of B, we use the vector $\vec{BC}$:
$C - B = \begin{pmatrix} 4 \\ 4 \end{pmatrix}$
$(6, 10) - (x_B, y_B) = (4, 4)$
$6 - x_
