Question

The vertices of a rectangle are given in the columns of the matrix R=[0 0 3 3 0 3 3 0]. If [-1 0 0 1]x R is found to perform a transformation, what are the coordinates of the transformed rectangle?
(0, 0), (0, -3), (-3, -3), (-3,0)
(0,0), (0, 3), (3, 3), (3,0)
(0,0), (0, 3), (-3, -3), (-3,0)
(0,0), (0, 3), (-3, 3), (-3,0)

Answer 1

Answer:

  (0,0), (0, 3), (-3, 3), (-3,0)

Step-by-step explanation:

The matrix multiplication is shown in the attachment. The transformed coordinates are ...

  (0,0), (0, 3), (-3, 3), (-3,0)

_____

You can count the instances of -3 in the result matrix to choose the correct answer.
