Answer:
m (slope) = 13/-39 (13 over -39)
Step-by-step explanation:
To find the slope by using two points, we do rise over run (y over x)
y2-y1 (the numbers 1 and two don't matter, it's just to be sure that each point's numbers line up, for example, that -19 and 20 line up, and that 20 and 7 line up)
x2-x1
20-7 = 13
-19-20 = -39
Then, simplify
13/-39 cannot be simplified, so that is your answer.
