How do you determine the scale for a graph?

Back

The scale for a graph is determined by the range of data values and should be evenly spaced to accurately represent the data.

Front

What is the importance of labeling axes in a graph?

Back

Labeling axes is crucial for clarity, allowing viewers to understand what variables are being represented and their units of measurement.
