Answer:
Rise/run = - 4/3
The rise is vertical, run is from left to right. I counted 4 units down from (-3, 2) to (-3, -2) and since it is down, it's negative. Then, I counted 3 units to the right from (-3, -2) to (0, -2) and the run will always be positive. Because there is a negative in one of the numbers, the slope will be negative: - 4/3
