The graphs show that the U.S. public has taken a more conservative stance on gun control for the period from 1999 through 2009. a. Write the slope-intercept equation of the line that models the percentage of the U.S. public that favors gun control, y, x years after 1999. b. Write the slope-intercept equation of the line that models the percentage of the U.S. public against gun control, y, x years after 1999. c. Use the models from parts (a) and (b) to project the year, to the nearest whole year, during which the percentage in favor of gun control was the same as the percentage against gun control. What percentage of the U.S. public, to the nearest percent, shared each of these opinions during that year?
