Help with this math problem plz

A'(-3,3)

Step-by-step explanation:

 Point A of the triangle is 2 units below the line. Therefore when refelected over the line, point A will be 2 units above the line. 2 units above the line, y=1, is 3.

 Since the triangle is being reflected over y=1, the x coordinate will stay the same, but the y coordinate will change. (If the line was being reflected over x=1, then the y coordinate would stay and the x coordinate would change).

Therefore the new y coordinate will be 3, and the x coordinate will be the same as it was before, -3.
