What is the significance of the scale on a graph?

Back

The scale on a graph determines the range of values displayed and ensures that the data is represented accurately and proportionally.

Front

What is a key in a graph?

Back

A key explains the symbols, colors, or patterns used in the graph to differentiate between different data sets or categories.
