Reading Line Graph

Front

What is a line graph?

Back

A line graph is a type of chart that shows information as a series of data points called 'markers' connected by straight line segments.

What does the x-axis represent in a line graph?

Back

The x-axis typically represents the independent variable, which is the variable that is changed or controlled in a scientific experiment.

Front

What does the y-axis represent in a line graph?

Back

The y-axis usually represents the dependent variable, which is the variable that is measured in the experiment.

Front

How do you read a line graph?

Back

To read a line graph, look at the x-axis to find the category, then move up or down to see the corresponding value on the y-axis.

Front

What does an upward slope in a line graph indicate?

Back

An upward slope indicates that the value of the dependent variable is increasing as the independent variable increases.

Front

What does a downward slope in a line graph indicate?

Back

A downward slope indicates that the value of the dependent variable is decreasing as the independent variable increases.

Front

What does a flat line in a line graph indicate?

Back

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

Front

What is the purpose of a title in a line graph?

Back

The title of a line graph explains what the graph is about and what data is being represented.

Front

What is a data point in a line graph?

Back

A data point is a specific value plotted on the graph, representing the relationship between the independent and dependent variables.

Front

How can you identify trends in a line graph?

Back

Trends can be identified by observing the overall direction of the line, whether it is increasing, decreasing, or remaining constant.
