Question

4 how are multiple sources of data represented in a line graph? different - colored lines on the same gridlines additional columns and/or rows different - colored bars on the same gridlines different - colored lines on different gridlines

Explanation:

To determine how multiple data sources are represented in a line graph, we analyze each option:

• "Additional columns and/or rows" is for tables, not line graphs.
• "Different - colored bars on the same gridlines" describes a bar graph, not a line graph.
• "Different - colored lines on different gridlines" would make comparison difficult and is not the standard way; line graphs use the same grid for multiple lines to enable easy comparison.
• "Different - colored lines on the same gridlines" is correct because in a line graph, multiple data sets are plotted as lines of different colors (or styles) on the same set of axes (gridlines) to allow for visual comparison of trends.

Answer:

A. Different - colored lines on the same gridlines
