Answer:

-4.5

Step-by-step explanation:

We will use a graphing calculator to find the line of best fit and the corresponding regression equation.

First we enter the x values into the first list.  Then we enter the y values into the second list.

We pull up the graph (attached).  Next we calculate the linear regression (screenshot attached).  In the regression, we can see that the slope is -4.5 (rounded to the nearest tenth).
