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. It is used to display data that changes over time.

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

Back

The x-axis (horizontal axis) typically represents the independent variable, which is the variable that is changed or controlled in an experiment.

Front

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

Back

The y-axis (vertical axis) usually represents the dependent variable, which is the variable that is measured or affected in an experiment.

How do you read a line graph?

Back

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

What does it mean if a line on a graph is going up?

Back

If a line on a graph is going up, it means that the value of the dependent variable is increasing over time.

How can you find the total amount from a line graph?

Back

To find the total amount from a line graph, you can add the values of the data points together.

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

Back

The title of a line graph explains what the graph is about, providing context for the data being presented.

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.
