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=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 11,160?
Y = -1777X + 27153.
1. Yr 2006:
Y = -1777*6 + 27153,
Y = -10662 + 27153 = 16491.
2. Yr 2007: You can try this one.
3. Y = -1777X + 27153 = 11160,
-1777X + 27153 = 11160,
Solve for X.
