When interpreting a line graph, what does the slope represent?

• A. The total value of the dependent variable
• B. The rate of change of the dependent variable with respect to the independent variable
• C. The average value over the time period of the graph
• D. The maximum point of the independent variable

Answer: (B)

The slope of a line graph represents the rate of change of the dependent variable with respect to the independent variable. This means that the slope indicates how much the dependent variable changes for each unit change in the independent variable. For example, if the line graph represents distance over time, the slope would give the speed, or how much distance is covered per unit of time. In essence, a steeper slope indicates a faster rate of change, while a flatter slope indicates a slower rate of change. This concept is fundamental in interpreting line graphs, as it allows one to understand trends and relationships between the variables being graphed.
