Suggestion: Students should create the graph on the Desmos website.  Students click on "start graphing" then they click on the plus sign to the left and add a table to start inserting the data. 

Completing this task on Desmos familiarizes students with using the site, which is part of the Virginia Standards of Learning. This particular task uses coordinates that are difficult to recreate on a hand drawn graph. Using the "Table" tool in Desmos creates a more accurate graph. Students are still able to use dry spaghetti in order to see a line of best fit and determine outliers.
