An urn contains n balls numbered 1, 2, 4, 8, etc. up to 2n-1 where n > 1. If a person selects one ball from the urn and then replaces it and selects a second ball, what is the expected value of the sum of the balls' numbers?

By making this change, the graph would shift vertically. The graph would maintain the same slope with downward motion. The entire graphed line (since the function is linear) would shirt down to where the y-intercept was a -3 rather than a 2. This is a change of 5 units.

So the graph would shift 5 units down.

I hope this helps! :)
