Answer:
slopee = 5/3
Step-by-step explanation:
The  slope of a line is defined by the rise (the change in y-value) divided by the run (the change in x-value).  Here, the change in y-value is 6 - (-14) = 6 + 14 = 20.  The change in x-value is 20 - 8 = 12.  Therefore, the slope is 20/12 or (simplified) 5/3.
