The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states.
xx | 11.9 | 8.6 | 6.9 | 3.5 | 2.6 | 2.8 | 2.4 | 0.3 |
---|---|---|---|---|---|---|---|---|
yy | 13.9 | 11.2 | 9.6 | 7.1 | 6.1 | 6.2 | 6 | 4.5 |
xx = thousands of automatic weapons
yy = murders per 100,000 residents
This data can be modeled by the equation y=0.82x+4.07.y=0.82x+4.07. Use this equation to answer the following;
