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.

Front

What does a line graph typically show?

Back

A line graph typically shows how a quantity changes over time, allowing for easy visualization of trends and patterns.

How do you read a line graph?

Back

To read a line graph, look at the x-axis (horizontal) for the time intervals and the y-axis (vertical) for the values. Follow the line to see how the values change over time.

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

Back

The x-axis in a line graph represents the independent variable, often time, showing the intervals at which data is collected.

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

Back

The y-axis in a line graph represents the dependent variable, showing the values or measurements that change in response to the independent variable.

Front

What does it mean if a line on a graph is increasing?

Back

If a line on a graph is increasing, it means that the value of the dependent variable is rising over the time intervals represented on the x-axis.

What does it mean if a line on a graph is decreasing?

Back

If a line on a graph is decreasing, it means that the value of the dependent variable is falling over the time intervals represented on the x-axis.

What is a data point in a line graph?

Back

A data point in a line graph is a specific value plotted on the graph, representing the measurement at a particular time.

Front

How can you determine the highest value on a line graph?

Back

To determine the highest value on a line graph, look for the highest point on the line, which corresponds to the maximum value on the y-axis.

Front

How can you determine the lowest value on a line graph?

Back

To determine the lowest value on a line graph, look for the lowest point on the line, which corresponds to the minimum value on the y-axis.
