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.

How do you determine the slope of a line in a line graph?

Back

The slope of a line in a line graph is determined by the change in the y-value divided by the change in the x-value between two points.

Front

What does an upward slope indicate in a line graph?

Back

An upward slope indicates that the dependent variable is increasing as the independent variable increases.

Front

What does a downward slope indicate in a line graph?

Back

A downward slope indicates that the dependent variable is decreasing as the independent variable increases.

Front

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

Back

The highest point on a line graph is found by identifying the maximum y-value among the data points.

Front

What does a flat line indicate in a line graph?

Back

A flat line indicates that there is no change in the dependent variable as the independent variable changes.

Front

How can you compare two sets of data on a line graph?

Back

You can compare two sets of data by plotting them on the same graph with different lines, allowing you to see trends and differences.

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

Back

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