Question

multiple - choice question
why should you have titles on your graph (at the top and on each axis)?
titles describe the graph
titles help you create the graph

Explanation:

Titles on a graph (top - overall title and axis titles) are used to describe what the graph represents. They give context about the data being shown, such as what variables are on each axis and what the overall data set is about. They do not help in creating the graph, but rather in understanding it.

Answer:

Titles describe the graph
