A. Erin basically put 2 units to the right and 4 units down. Since x would be going left or right and y up or down, Erin did not write the rule correctly.

b. The correct transformation rule would be (x, y) (x - 4, y + 2). When going to the left, you would be subtracting and going up would be adding, hope this helped!
