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 = 3 corresponds to 2003, x = 6 corresponds to 2006, and so on. Predict the number of gun deaths in 2006 and 2009. In what year will the number of gun deaths be 9383?

Question

Henry · Answer

Y = -1777X + 27,153.

1.For 2006, substitute 6 for X and solve the Eq.

2. F0r 2009 substitue 9 for X and solve
Eq.

3. Y = -1777X + 27,153 = 9383,
-1777X + 27,153 = 9383,
-1777X = 9383 - 27153 = -17770,
X = 10 Deaths.
