Answer:
5. reduction 6.enlargement
Step-by-step explanation:
if the scale factor is greater than one (for example) 2 then it will enlarge, but if the scale factor is less than one, it is reduced.
An in #5, from A to B the rectangle goes from bigger (A) to smaller (B) so it must have a smaller scale factor in order to reduce ,and in #6 A is smaller and B is bigger which goes back to the concept of it must have a bigger scale factor in order for it to enlarge. But all in all you can see in #5 A. is the bigger rectangle so in order to become the rectangle in B. it must reduce.
The coefficient matrix is
Notice that the last row is -4 times the first row, so that the rows of the matrix are not independent. This means the determinant would be 0.
Just to confirm, we can compute the determinant via a Laplace expansion along the first row:
