Answer 1

The statement that best describes a line graph is:

• C. It shows a line that connects a series of data points.

A line graph is a graphical representation of data that uses a line to connect a series of data points. Each data point represents a specific value and the line connects these points to illustrate trends, patterns or changes over a continuous interval or time period.

Line graphs are commonly used to visualize data that shows how a variable changes over time or in relation to another variable. They are particularly useful for displaying trends, identifying correlations or comparing multiple data sets.
