Question

I have seen examples of this but the examples are not helping me solve it or set it up as a y=mx +b
The equation y= -1777x + 27,153 can be used to predict the number of gun deaths in the U.S. x years after 2000, x=0 corresponds to 2000 x=3 corresponds to 2003, x=5 corresponds to 2005 Predict the number of gun deaths in 2005 and 2008. In what year will gun deaths be 11,160 ?

2005:
2008:
When will gun deaths reach 11,160 in a year:

Answer 1

Y = -1777 (5) + 27153 = -8885 + 27153=
18268.
Y = -1777(8) + 27153 = 12937.

Y = -1777X + 27153 = 11160
-1777X = -15993
X = 9 = yr. 2009

Answer 2

thank you Henry. I love the story problems but this one was a bit much.
