Front

What is a line graph?

Back

A line graph is a type of graph that shows how something changes over time by connecting points with a line.

Front

What kind of data is best represented by a line graph?

Back

Line graphs are best for showing continuous data, such as changes in temperature or population over time.

Front

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

Back

The x-axis typically represents the time or categories being measured.

Front

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

Back

The y-axis represents the values or quantities being measured.

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 values change.

Front

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

Back

A flat line means that the value is constant and does not change over the time period shown.

Front

What does an upward slope on a line graph indicate?

Back

An upward slope indicates that the value is increasing over time.

Front

What does a downward slope on a line graph indicate?

Back

A downward slope indicates that the value is decreasing over time.

Front

How can you find the total from a line graph?

Back

To find the total, you may need to add the values at specific points on the graph.

Front

What is a data point in a line graph?

Back

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