Line graph

Front

What is a line graph?

Back

A line graph is a type of chart that shows information as a series of data points called 'markers' connected by straight line segments.

Front

What does the slope of a line in a line graph represent?

Back

The slope of a line in a line graph represents the rate of change between the two variables being compared.

Front

How do you read a line graph?

Back

To read a line graph, look at the x-axis (horizontal) for one variable and the y-axis (vertical) for the other variable. Follow the line to see how the values change.

Front

What does it mean if a line on a graph is going up?

Back

If a line on a graph is going up, it means that the value of the variable on the y-axis is increasing as the value of the variable on the x-axis increases.

Front

What does it mean if a line on a graph is going down?

Back

If a line on a graph is going down, it means that the value of the variable on the y-axis is decreasing as the value of the variable on the x-axis increases.

Front

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

Back

The title of a line graph explains what the graph is about and what data is being represented.

Front

What are the axes of a line graph?

Back

The axes of a line graph are the two lines that form the graph: the x-axis (horizontal) and the y-axis (vertical).

Front

What does a flat line on a graph indicate?

Back

A flat line on a graph indicates that there is no change in the value of the variable on the y-axis as the variable on the x-axis changes.

Front

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

Back

To find the highest point on a line graph, look for the highest point on the y-axis that the line reaches.

Front

What does a steep line on a graph indicate?

Back

A steep line on a graph indicates a rapid change in the value of the variable on the y-axis as the variable on the x-axis changes.
