Front

What is the purpose of a graph?

Back

The purpose of a graph is to visually represent data to make it easier to understand and analyze relationships between variables.

Front

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

Back

If a line on a graph is increasing, it indicates that the dependent variable is rising as the independent variable increases.

Front

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

Back

If a line on a graph is decreasing, it indicates that the dependent variable is falling as the independent variable increases.

Front

What is a data point?

Back

A data point is a single value or measurement that is plotted on a graph.
