Step 1: Select a value for . It can be anything you like, but generally speaking, small integers make for easier arithmetic. Given the coefficient on in your problem, a small even integer would be a good choice.
Step 2: Substitute the value you chose in Step 1 for in your function and then do the arithmetic required to determine the value of .
Step 3: Create an ordered pair, , consisting of the value you selected in Step 1 and the value you calculated in Step 2.
Step 4: Plot the point you created in Step 3 on an appropriately scaled set of coordinate axes.
Step 5: Repeat Steps 1 through 4 selecting a different value for .
Step 6: Draw a line through the two plotted points all the way across the graph.
