What is the most appropriate type of graph to use to compare the masses of eight planets? a. a line graph b. a circle graph c. a proportion graph d. a bar graph

The most appropriate type of graph to use to compare the masses of eight planet is a bar graph. Bar graphs (also called bar charts) are horizontal columns charts that are well suited to show the relative size of the variable (masses of planets), they permit to write long names easily and are specially good for more than seven categories and less than fifteen. Try this graph and you will see that you can easily compare the order of the masses.
