Line Graphs

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. It is used to display trends over time.

What does a line graph typically show?

Back

A line graph typically shows how a quantity changes over time, allowing us to see trends and patterns.

Front

What is the x-axis in a line graph?

Back

The x-axis is the horizontal line on a graph that usually represents the independent variable, such as time.

Front

What is the y-axis in a line graph?

Back

The y-axis is the vertical line on a graph that usually represents the dependent variable, such as quantity or value.

Front

How do you read a line graph?

Back

To read a line graph, look at the points plotted on the graph and follow the lines to see how the values change over time.

Front

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.

Front

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

Back

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

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

What is the purpose of a line graph?

Back

The purpose of a line graph is to show trends over time, making it easier to visualize changes in data.

Front

What can you infer from a flat line on a graph?

Back

A flat line on a graph indicates that there is no change in the value of the dependent variable over time.
