To transform the first graph to make it become a non-proportional graph with the same y-intercept as the second graph, you would need to add a fixed fee to each point on the first graph. In this case, the fixed fee is $20.

So, for each point (x, y) on the first graph, you would transform it to (x, y+20) on the non-proportional graph. This means moving each point on the first graph upward by 20 units.
