How do you read the height of a sunflower from a graph?

Back

To read the height of a sunflower from a graph, locate the week on the horizontal axis and find the corresponding height on the vertical axis.

Front

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

Back

A steep line on a graph indicates a rapid change in value. For example, if the height of a sunflower increases quickly, the line will be steep.

Front

What is the purpose of a title on a graph?

Back

The title of a graph explains what the graph is about, helping the viewer understand the data being presented.

Front

What does the vertical axis represent in a line graph?

Back

The vertical axis (y-axis) typically represents the quantity being measured, such as height or population.

Front

What does the horizontal axis represent in a line graph?

Back

The horizontal axis (x-axis) usually represents the time or categories being measured, such as weeks or years.

Front

How can you determine the fastest growth from a graph?

Back

You can determine the fastest growth by looking for the steepest line on the graph, which indicates the greatest increase in value over time.

Front

What is an example of data that can be represented on a line graph?

Back

An example of data that can be represented on a line graph is the height of a sunflower measured weekly.

Front

What does it mean if two lines on a graph intersect?

Back

If two lines on a graph intersect, it means that the two data sets have the same value at that point in time.

Front

What is a data point?

Back

A data point is a single value that represents a measurement or observation in a graph.
