The question is asking you to organize the data in line plot form. to do so you must create a number line (which in this case is provided for you) and put X's above the numbers. for example lets say your given the following data : 1, 2 ,2 , 4 , 1 , 3 , 2 , 5 this is how you would graph it in line plot form
but in your case not al the numbers listed are on the plot so instead you do this: x . x x . x . x . x . x ___________________________________ 1 . 3 . 5 . plot as if the numbers are there. ( as usual spacing is important)
