Answer: -2/7
This value is a fraction.
----------------------------------
Work Shown:
The first two rows in the table produce these two points (x1,y1) = (-14,8) and (x2,y2) = (-7,6)
So, x1=-14, y1=8, x2=-7, and y2=6
Plug these four values into the slope formula and simplify
m = (y2 - y1)/(x2 - x1)
m = (6 - 8)/(-7 - (-14))
m = (6 - 8)/(-7 + 14)
m = -2/7

Hope this helped ;)
By the law of cosines, the angle

satisfies

which reduces to

which converts to approximately 77 degrees (this can be done my multiplying by 180 and dividing by pi).
