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.

1 answer

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?
