It would only remain the same if graph 2 had the exact same points of graph 1 or if every point on graph 2 had a 2nd point that was the same distance on the other side of graph 1. That may sound a little confusing that last statement, but the idea is that it would not remain the same. 

Take a look at graph 1 and find some points we dont have to even approximate. I see a point (5,20) on graph 1 (5C = 20 dollars in ice cream), and I also see (10, 30), (15, 40) and so on. So when I look at graph 2, Im going to find those points, (5,20), (10,30), etc, and see if the points on graph 2 are mostly below or above those values.

I have to pack up my laptop and head out now, but hopefully that makes sense. The points on graph are definitely on one side of those guaranteed points I mentioned. It should point you in the right direction. Good luck :)
