Someone please help me with this

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 the year 2000. x=3 corresponds top 2003x=6 corresponds to 2006 and son on. Predict the number of gun deaths in 2006 and 2009.In what year will the number of gun deaths be 9383?

  • Algebra - ,

    Use the equation you were given. y is the number of gun deaths. For 2006, use x = 6. For 2009, use x = 9.

    To solve the last part, solve
    9383 = 27153 - 1777 x to get x. You should get x = 10

    Add x to 2000 to get the year.

    There is no reason to expect past performance (represented the equation) to represent the future, but that is what they want you to do here. Gun deaths will probably start rising again.
