Analyze Line Graphs

What is a line graph?

Back

A line graph is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments. It is used to show trends over time.

How do you read a line graph?

Back

To read a line graph, look at the x-axis (horizontal) for the independent variable and the y-axis (vertical) for the dependent variable. Follow the lines to see how the values change.

What does the slope of a line in a graph represent?

Back

The slope of a line in a graph represents the rate of change between the two variables. A steeper slope indicates a greater rate of change.

What does it mean if a line graph is increasing?

Back

If a line graph is increasing, it means that the value of the dependent variable is rising as the independent variable increases.

What does it mean if a line graph is decreasing?

Back

If a line graph is decreasing, it means that the value of the dependent variable is falling as the independent variable increases.

What is a data point in a line graph?

Back

A data point in a line graph is a specific value that represents the relationship between the independent and dependent variables at a given time.

Front

How can you identify trends in a line graph?

Back

You can identify trends in a line graph by observing the overall direction of the line (upward, downward, or stable) over a period of time.

Front

What is the importance of the x-axis in a line graph?

Back

The x-axis in a line graph represents the independent variable, which is the variable that is manipulated or changed.

Front

What is the importance of the y-axis in a line graph?

Back

The y-axis in a line graph represents the dependent variable, which is the variable that is measured or observed.

Front

What does a flat line indicate in a line graph?

Back

A flat line in a line graph indicates that there is no change in the dependent variable as the independent variable changes.
