The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states.

 xx yy 11.5 8.4 7 3.9 2.7 2.6 2.3 0.7 14.1 11.4 10.1 7.5 6.4 6 6.1 4.5

xx = thousands of automatic weapons
yy = murders per 100,000 residents

The equation y=3.93+0.89xy=3.93+0.89x can model this data. Use this equation to answer the following;
Special Note: I suggest you verify this equation by performing linear regression on your calculator.

A) How many murders per 100,000 residents can be expected in a state with 2 thousand automatic weapons?

Answer =  Round to 3 decimal places.

B) How many murders per 100,000 residents can be expected in a state with 4 thousand automatic weapons?

Answer =  Round to 3 decimal places.

The euation is y = 0.7515x + 60.439

y=3.93+0.89x

A.

x=2000

y=3.93+0.89(2000)

y= 178.93

179.93 murders per 100,000 residents can be expected in a state with 2 thousand automatic weapons

b.

x=4000

y=3.93+0.89(4000)

y= 356.930

357 murders per 100,000 residents can be expected in a state with 4 thousand automatic weapons?

Hope this helps !!
