The writing isnt so clear to me
Have a look at the first elements of each point: {3, 0, 1, -2, 2}. Since these are all different, no one x value has more than one y-value associated with it, and thus (3,-2)(0,1)(1,0)(-2,-1)(2,-1) is a function.
I think you meant "y = 4 arccot (x)."
This is equivalent to:
y
---- = arccot x
4
and so cot (y/4) = x
Answer:

12m + 4c = 10m + 3c + 8
Combining like terms:
2m + c = 8
