In the original graph, R (0,3), S(3,3), T(4, -1) and Q(0, 1) Reflecting it across y=-1, which is a horizontal line going through the point T, all the x coordinates stay the same, the new confidantes are : R'(0, -5), S'(3, -5), T'(4, -1), Q(0', -3) (Notice; T stays where it is now, because it is right now the line y=-1) Locate these new points, you have your graph.
3the relationship is the shapes are the same just dilated and in different spots. The shapes are in different spots and are different sizes ut they are the same shape making them related.
