A shift in the relationship shown in Exhibit 1A-7 would only occur if there was a change in the price of air travel, which is the only variable represented on the vertical axis. A rise in people's income or expenditure on air travel would not directly affect the relationship shown in the exhibit, as they are not represented on the graph.
