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, such as 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, 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 or categories.

Front

What does it mean if a line on a graph goes up?

Back

If a line on a graph goes up, it indicates that the value of the dependent variable is increasing.

Front

What does it mean if a line on a graph goes down?

Back

If a line on a graph goes down, it indicates that the value of the dependent variable is decreasing.

Front

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

Back

If a line on a graph is flat, it means that the value of the dependent variable is staying the same over the period shown.

Front

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

Back

The highest point on a line graph is where the line reaches its peak; this indicates the maximum value of the dependent variable.

Front

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

Back

The lowest point on a line graph is where the line dips to its lowest; this indicates the minimum value of the dependent variable.

What is a data point in a line graph?

Back

A data point is a specific value plotted on the graph, representing the intersection of the x and y values.
