Multiply the matrix representing the vertices of the rectangle to transform the figure.What are the coordinates of the resulting figure? (0, 0), (4, 0), (4, 4), (0, 2)(0, 0), (–4, 0), (–4, –4), (0, 2)✔ (0, 0), (4, 0), (4, –4), (0, –2)(0, 0), (–4, 0), (–4, -4), (0, –2)

The following transformation uses both scalar and matrix multiplication.What are the coordinates of the resulting figure? (0,0), (4, 0), (4, –2), (0, –4)(0, 0), (8, 0), (8, –4), (0, –8)(0, 0), (–8, 0), (–8, 4), (0, 8)✔ (0, 0), (0, –8), (–4,–8), (–8,0)

Do these procedures yield the same result?1. First do the scalar multiplication, then do the matrix multiplication.2. First do the matrix multiplication, then do the scalar multiplication.
