The equation y = 1777x + 27,152 can be used to predict the number y of gun deaths in the United States. x years after 2000, that is x=0 corresponds to 2000: x = 2 corresponds to 2002, x = 5 corresponds to 2005, and so on. Preddict the number of gun deaths in 2005 and 2007. In what year will the number of gun deaths be 11,160.
For 2005, use the equation
y = 1777x + 27,152
and substityute 5 for x.
For 2007, use the equation
y = 1777x + 27,152
and substitute 7 for x.
For the third part, use
For 2005, use the equation
11,160 = 1777x + 27,152
and solve for x. It will be -9, so the year will be 9 years BEFORE 2000.
How about 1991?
