Explanation:

Analyze sales trends over time

To identify trends over a continuous period (such as months over the past year), a line graph is the most effective visualization tool because it clearly displays changes and directions over time.

Determine the sum of percentages in a pie chart

A pie chart represents a whole entity, which corresponds to 100% of the data being visualized.

Identify the purpose of scale in charts

A scale is used in charts and graphs to represent data values proportionally, allowing large numbers to be accurately and readably displayed within the visual space.
