4. A properly constructed graph follows these guidelines: Descriptive title Both axes labeled correctly Appropriate intervals Data points plotted neatly Line connecting data points drawn with a ruler Use the whole page of graph paper!

5. A properly constructed data table follows these guidelines: A descriptive title Variables describing what information has been collected Units telling how those variables were measured Data collected in order pairs
