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.

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

Back

The x-axis (horizontal axis) typically represents the independent variable, often time or categories.

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 value being measured.

Front

How do you read a line graph?

Back

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

Front

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

Back

A flat line indicates that there is no change in the value of the dependent variable over the time period represented.

Front

What does an upward slope on a line graph indicate?

Back

An upward slope indicates an increase in the value of the dependent variable as the independent variable increases.

Front

What does a downward slope on a line graph indicate?

Back

A downward slope indicates a decrease in the value of the dependent variable as the independent variable increases.

Front

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

Back

The title provides a clear description of what the graph represents, helping viewers understand the data being presented.

Front

How can you identify the highest point on a line graph?

Back

The highest point on a line graph is where the line reaches its maximum value on the y-axis.

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.
