SOLUTION:
The number of gun deaths y in 2006 can be found by substituting x = 6 into the formula y=-1,777x+27,153.
y = -1,777*6 + 27,153 = 16,491
The number of gun deaths y in 2006 can be found by substituting x = 7 into the formula y=-1,777x+27,153.
y = -1,777*7 + 27,153 = 14,714
To find in what year the number of gun deaths will be 11,160, solve the following equation for x:
-1,777x+27,153 = 11,160
1777x = 15993
x = 9
So in 2009 the number of gun deaths will be 11,160.
