A line graph, titled Amount of Air Pollution Parcticles by State, shows Parts per trillion or p p t, and Years 2006 through 2015 for Virginia, Wyoming, North Carolina, Tennessee, and Maryland. The line for Wyoming starts at 5 p p t with little change, ending just below 5 p p t. The line for Virginia starts at 13 p p t and ends at 8 p p t. The line for North Carolina starts at 13 p p t and ends just below 9 p p t. The line for Maryland starts just above 13 p p t and ends at 10 p p t. The line for Tennessee starts near 13.5 and ends at 9 p p t. Use the graph to answer the following questions.

Which state has the highest level of air pollution particles for the year 2014?

Which state shows the least change in air pollution particles from 2006 to 2015?

What action is most likely to have helped reduce the rate of air pollution particles?

a. Maryland

b. Wyoming

c. Government regulations

Explanation:

For Wyoming, we have;

2006: 5 p p t

2015: < 5 p p t

For Virginia, we have;

2006: 13 p p t

2015:  8 p p t

For North Carolina, we have;

2006: 13 p p t

2015: 9 p p t

For Maryland, we have;

2006: 13 p p t

2015: 10 p p t

For Tennessee, we have;

2006: 13.5 p p t

2015: 9 p p t

a. Based on the linear graphs, the state that has the highest level of air pollution particles is given by the relation

Therefore, for Wyoming, we have;

For Virginia, we have;

For North Carolina, we have;

For Maryland, we have;

For Tennessee, we have;

Therefore, Maryland has the highest level of air polluton particles for the year 2014

b. From the available data, Wyoming shows the least change in air pollution particles from 2006 to 2015 with a change from 5 p p t to < 5 p p t

c. Regulations which limit the amount of particles from pollutants that can be released into the Air.
