Chapter 3 - Section 3.1 - Graphing Equations - Exercise Set: 83


The graph is a broken-line graph because the hourly minimum wage does not increase continuously. Rather, the hourly minimum wage is usually increased by intervals over time.

The government usually decides to increase the hourly minimum wage by an interval every few years. Therefore, this graph accurately depicts how the minimum wage jumps between two consecutive time periods. The size of the jump (or the increase in y-coordinate on the graph) represents how much the minimum wage is increased at a given time.
