Interpret Line Graphs (Level 2)

Front

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 it mean when a line on a graph goes up?

Back

When a line on a graph goes up, it indicates that the value represented by the line is increasing over the period shown.

Front

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

Back

When a line on a graph goes down, it indicates that the value represented by the line is decreasing over the period shown.

Front

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

Back

A flat line on a graph indicates that the value represented by the line is staying the same over the period shown.

Front

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

Back

The highest value on a line graph can be determined by identifying the highest point on the line.

Front

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

Back

The lowest value on a line graph can be determined by identifying the lowest point on the line.

Front

What does it mean if a data point is above a certain value on a line graph?

Back

If a data point is above a certain value on a line graph, it means that the value represented is greater than that specific value.

Front

What does it mean if a data point is below a certain value on a line graph?

Back

If a data point is below a certain value on a line graph, it means that the value represented is less than that specific value.

Front

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

Back

The x-axis typically represents the independent variable, often time, showing how the dependent variable changes over that period.

Front

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

Back

The y-axis typically represents the dependent variable, showing the values that are being measured or observed.
