Some line graphs have separate lines for different items. By plotting the different sets of data on the same graph, you can make a comparison between the sets of data.
B. The line included in the graph below shows the level of unemployment in a state over a seven-year period. below are the corresponding unemployment rates rates for Middleboro, a major city in this state. Use a different colored pen, pencil, or marker to plot these points on the graph.

| Year 1: 4.4% | Year 3: 9.3% | Year 5: 10.1% | Year 7: 7.1% |
| Year 2: 6.1% | Year 4: 12.2% | Year 6: 7.6% | |
