Answers to Questions on Line Graphs

1. The minimum wage in January, 1978, reached $2.65. This could be determined by finding January, 1978 on the x-axis and following it up until you hit the line.

2. The minimum wage reached reached $3.35 in January, 1981. This answer could be reached by finding $3.35 on the line and following it down until you hit the x-axis.

3. The largest increase in minimum wage was between April, 1991, when it was $4.25, and October, 1996, when it reached $4.75. This $0.50 increase was the largest one displayed on the graph.

4. This was a tricky question, because the time periods in between each increase are different. Because of this, there is not a constant rate at which the minimum wage increases. It is possible that the wage would not increase at all by 2000. If it did increase, however, judging by past increases, it would probably be an increase of about $0.45. Therefore, a good guess based on this graph, would be that the minimum wage in 2000 will be anywhere from $5.15 to $5.60.

5. If you looked carefully at the x-axis, you would see that even though each time period is marked an equal distance apart, they are not really consistent time differences. For instance, the graph goes from April, 1990 to April, 1991 to October, 1996. Obviously, there is one year between the first two, while there are over five years between the second two. This inconsistency will make the data appear differently than how it really is.
