I uploaded a picture of it to the internet.

Answer 1

1// In 2005 x = 5 since x = 2005-2000

y = -1777 x 5 + 27,153

y = -8885 + 27,153

y = 18,268

2// Same method as above  

     x=7

     y=14717

3//  If the number of deaths = 11,160 then y = 11,160

11,160 = -1777x + 27,153

Minus 27,153 from both sides

-15993 = -1777x

Divide both sides by -1777

x = 9

=> 2009

Answer 2

frst re-write the problem then substitute in the 5 in place of the x and solve for your answer of gun deaths, then do the same plugging in the 7.

after that re-write the original problem but set it equal to the 11,160. solve as a two-step and associate your answer with the "x=5 is 2005."

-1, 777x + 27, 153 = z (random variable not associated with x or y)

-1, 777(5) + 27, 153 = 18, 268

-1, 777(7) + 27 ,153 = 14, 714

-1, 777x + 27, 153 = 11, 160

              - 27, 153   - 27, 153

-1, 777x = - 15, 993

<divide both sides by the -1, 777>

x= 9, year 2009.

Answer 3

Just plug in 5 and 7 for x in the first two questions.  Then you can find the value of y.

In the last one, plug in that number for y, and you should be able to figure the value of x, which is the year.

Answer 4

you need to set it up in your graphing calculator

Answer 5

Just replace x with the year number -2000
