Final answer:
The differences between blended and dual axis are: blended axis combines different types of data on a single graph, while dual axis uses two separate axes, and blended axis shows a relationship between two variables while dual axis compares two variables with different units.
Step-by-step explanation:
Blended and dual axis are two different types of graphs that are used to represent data visually.
The first difference between blended and dual axis is that blended axis combines different types of data on a single graph, while dual axis uses two separate axes to represent different types of data.
The second difference is that blended axis can be used to show a relationship between two variables, while dual axis can be used to compare two variables that have different units of measurement.
