Thank you for answering, still I don't completely know how looking at A''(-x+4,y-6) you can determine there is a second reflection, I know first reflection over Y will be A' (-x,y), but do you get that the second is a reflection too and it is not a rotation.

Two transformations take place, the resultant change is A(x,y) ---A''(x+4, y-6), This is a result of a reflection in the y axis followed by a _________ (translation, reflection, rotation). I have the answer give by teacher as a "reflection, but I don't ...
