Answer:
-9/4 OR 9/-4
Explanation:
The simpilest solution is to do rise over run. This means you go up or down, and then you go across the x-axis.
In this case, you would move positive 9 upwards, and then go negative 4 spaces to the right. since 9 was the rise, it goes on top of the fraction, and since -4 was the run, you get -9/4 or 9/-4, both ending in a negative answer
