Question 248889
y= -1777x + 27,153 
2000 corresponds to x=0
2001 corresponds to x=1, etc.
y= -1777x + 27,153  [Substitute the year (x) into the equatiom and solve for the y-value]
y= -1777(6) + 27,153  [Substitute "6" for "x"]
y=16,491
y= -1777(8) + 27,153  [Substitute "8" for "x"]
y=12,937
11,160=-1777(x) + 27,153  [Since the amount "y" is given, substitute "11,160" solve for the x-term (year)]
11,160-27,153=-1777(x) + 27,153
-15,993=-1777x
-15993/-1777=-1777x/-1777
x=year 9 or 2009
