Which action best describes how to handle a graph when computing an answer is needed?

• A. Use only memory to compute the answer.
• B. Request and mark a printed copy of the graph.
• C. Ignore the graph and proceed.
• D. Ask another candidate for help.

Answer: (B)

When a problem involves a graph, you use the graph as your reference and interact with it directly. Requesting a printed copy and marking it lets you keep key data, scales, and relationships in front of you while you compute. Annotating the graph—circling important points, drawing lines to show relationships, or marking the x and y values you’re using—helps you read off numbers accurately, verify calculations, and see how changes in one variable affect another. This approach reduces reliance on memory and helps prevent misreading the graph.

Relying on memory alone can lead to mistakes, ignoring the graph means missing essential data it contains, and asking someone else for help isn’t appropriate in an exam setting and doesn’t address how you should approach solving the problem.
