Question 203357
The equation y= -1777x + 27.153 can be used to predict the number y of the gun death in the United Stats X years after 2000, that is x=0 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 2007. In what year will the number of gun deaths be 12,937?
The predict gun deaths in 2006 will be ?
f(6) = -1777*(6) + 27.153 = -10634.847

Comment: That doesn't make any sense.  Check your problem statement.
