a. Write a matrix A that represents the coordinates of the quadrilateral. Place the x-coordinate of each point in the first row of A and the corresponding y-coordinate in the second row of A.
b. What operation on A will shift the graph of the quadrilateral 2 units upward?

• A) a. \(A = \left[ \begin{array} { r r r r } - 3 & 1 & 4 & - 2 \\ 2 & 5 & 3 & - 2 \end{array} \right]\) b. \(A + \left[ \begin{array} { l l l l } 2 & 2 & 2 & 2 \\ 0 & 0 & 0 & 0 \end{array} \right]\)
• B) a. \(A = \left[ \begin{array} { r r r r } 2 & 5 & 3 & - 2 \\ - 3 & 1 & 4 & - 2 \end{array} \right]\) b. \(A + \left[ \begin{array} { l l l l } 2 & 2 & 2 & 2 \\ 0 & 0 & 0 & 0 \end{array} \right]\)
• C) a. \(A = \left[ \begin{array} { r r r r } - 3 & 1 & 4 & - 2 \\ 2 & 5 & 3 & - 2 \end{array} \right]\) b. \(A + \left[ \begin{array} { r r r r } 0 & 0 & 0 & 0 \\ - 2 & - 2 & - 2 & - 2 \end{array} \right]\)
• D) a. \(A = \left[ \begin{array} { r r r r } - 3 & 1 & 4 & - 2 \\ 2 & 5 & 3 & - 2 \end{array} \right]\) b. \(A + \left[ \begin{array} { l l l l } 0 & 0 & 0 & 0 \\ 2 & 2 & 2 & 2 \end{array} \right]\)
