Question 186590
You are given:
y= -1777x+27153
.

-Predicted gun deaths in 2005 will be? 
x = 20005 - 2000
x = 5
Plugging it in:
y= -1777x+27153
y= -1777(5)+27153
y = 18268
.
-Predicted gun deaths in 2008? 
x = 20008 - 2000
x = 8
Plugging it in:
y= -1777x+27153
y= -1777(8)+27153
y = 12937
.
-Predicted gun deaths will be 11,160 in the year? 
11,160 is 'y' -- now, we solve for x:
y= -1777x+27153
11160 = -1777x+27153
11160 - 27153 = -1777x
-15993 = -1777x
-15993/-1777 = x
9 = x
