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. It is used to display data that changes over time.

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

Back

The y-axis is the vertical line on a graph that represents the values of the data being measured.

Front

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

Back

The x-axis is the horizontal line on a graph that represents the categories or time intervals for the data.

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 is the purpose of labeling axes in a line graph?

Back

Labeling axes helps to identify what each axis represents, making it easier to understand the data being presented.

Front

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

Back

If a line on a graph goes up, it means that the value of the data 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 means that the value of the data is decreasing.

Front

What is a data point in a line graph?

Back

A data point is a specific value plotted on the graph, representing a measurement at a certain time or category.

Front

How can you find the difference between two data points on a line graph?

Back

To find the difference, locate the two data points on the graph and subtract the smaller value from the larger value.

Front

What does a flat line on a graph indicate?

Back

A flat line indicates that there is no change in the value of the data over the time or categories represented.
