Answer:
4/5
Step-by-step explanation:
To be able to help you, I've had to assume that you meant one point was (11,12) and the other (-9,-4). Please practice your skills in inputting numerals and points.
If we go from (-9,-4) to (11,12), x increases by 20 and y increases by 16
Thus, the slope is m = rise / run = 16/20, or 4/5.
