use the data in the table to complete the missing line in the double line graph below. click to select points on the graph. usage of pen versus pencil

Explanation:

Step1: Identify data for pen

We look at the "Pen" column in the table for each year.

Step2: Plot points

For 2011, plot (2011, 100); for 2012, plot (2012, 100); for 2013, plot (2013, 0); for 2014, plot (2014, 250); for 2015, plot (2015, 200); for 2016, plot (2016, 100); for 2017, plot (2017, 250). Then connect these points with a line to complete the double - line graph for the usage of pen.

Answer:

Plot the points (2011, 100), (2012, 100), (2013, 0), (2014, 250), (2015, 200), (2016, 100), (2017, 250) and connect them with a line for the pen - usage line on the double - line graph.
