Groups: Discuss Problem B6, particularly what's going on in the table. Some observations that may arise are, "As x increases, y decreases, but by less and less each time." Or, "As y decreases, so does the amount by which it decreases." Or, "As y gets smaller, it does so at a slower and slower rate."
It's also important to think about the graph and whether it will cross either of the axes. Going back to the contexts of the problems (sharing money among several people, for example) should help make sense of the asymptotic nature of the graphs.
