Question

The equation y= -1777x+27,153 can be used to predict the number of gun deaths in the united States x years after 2000. Predict the number of gun deaths in 2006 and 2007. In what year will the number of gun deaths be 12,937?

Answer 1

y = -1777x + 27153

1 year after 2000 would be 2001

2006 and 2007 would be ? and ? years after 2000 respectively.

So we substitute these numbers for x, to get

y = -1777 * 6 + 27153

and

y = -1777 * 7 + 27153

Calculate those out for your answers.

The last part says:

-1777x + 27153 = 12937

so

-1777x = 12937 - 27153

Subtract and divide across by -1777 to get x.
