Answer: the slope is 1
Explanation:
Slope = Rise over Run. Rise= y run= x
For this problem the rise is the difference between 3 and 1 and the run is the difference between 0 and -2. The difference between 3 and 1 is 2 and the difference between 0 and -2 is also too. Which makes it 2/2 which simplifies to 1.
