The graphs show per capita consumption of soda and bottled water in the United States, in gallons, from 2000 through 2015.

a. Write the slope-intercept equation of the line that models soda consumption per capita, y, in gallons, x years after 2000.

b. Write the slope-intercept equation of the line that models bottled water consumption per capita, y, in gallons, x years after 2000.

c. Use the models from parts (a) and (b) to determine the year, to the nearest whole year, during which per capita soda consumption was the same as per capita water consumption.
