b) The equation y= - 1777x + 27,153 can be used to predict the Number y of gun deaths in the United States x years after 2000 that is x corresponds to 2000, x=2 corresponds to 2002, x = 6 corresponds to 2006, and so on. Predict the number of gun deaths in 2006 and 2008. In what year will the gun death be 9383?
