Question 189627: The equation y=-1777x+27,153 can be used to predict the number y of gun deaths in the U.S. x years after 2000. that is x=0 corresponds with the year 2000, x=2 for 2002, x=6 for 2006 and so on. Predict the number of gun deaths in the year 2006, and 2009.
2006=
2009=
What year will the gun deaths total 9383?

Let's put the Eqn y = -1777x + 27153 into graph and see the comparison of # of gun deaths vs year:

---> As you see, Number of Gun deaths is going down over the years.

Predicting Number of Gun Deaths in 2006 ==> x=6:
y=-1777%286%29%2B27153=+-10662%2B27153
highlight%28y=16491%29, Number of gun-deaths (2006)



Number of Gun deaths for 2009 ==> x=9:
y=-1777%289%29%2B27153+=+-15993%2B27153
highlight%28y=11160%29, Number of gun-deaths (2009)



Now, what year (x) when the gun deaths (y) total to 9383?

y=-1777x%2B27153
9383=-1777x%2B27153
9383-27153=-1777x
-17770=-1777x -----> cross%28-1777%29x%2Fcross%28-1777%29=cross%28-17770%2910%2Fcross%28-1777%29
highlight%28x=10yrs%29, Number of Years when deaths equal to 9383.
