Translating the point will subject the point to the rule whereby the new (x, y) is ([-1] + 4, [3] - 2), where the point has been substituted into the translation for you.  Simplify the point now.  Reflecting the point in the x-axis will keep the value of x the same but it will make y a negative value of what it was.
