Answer: The slope is 
Step-by-step explanation:
The slope can be calculated with the following formula:

Then, knowing that the line passes through the points (2,1) and (-1,-1), we can substitute the coordinates into the formula.
In this case:

Therefore, the slope of the line that passes through the points (2,1) and (-1,-1) is:
