Question

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 2000, x=3 corresponds to 2003, x=4 corresponds to 2004, and so on. Predict the number of gun deaths in 2004 and 2007. In what year will the number of gun deaths be 12,937?

Answer 1

Use the equation you were given and plug in 4 and 7 for x. See what numbers you get for y.

For the last part, solve the equation
12937= -1777x + 27,153
to obtain x.

These are certainly problems you can do yourself.
