Answer: C) There is no positive or negative correlation
A positive correlation is one where the values are increasing, and the line of dots are clearly going down to up.
A negative correlation is the opposite. The values are decreasing, and the line goes from up to down.
This correlation is one that is neither positive or negative. It is a straight line where the values neither increase nor decrease.

Answer:
d=1
Step-by-step explanation:
Factor d^2 - 2d - 8 into (d-4)(d+2)
Move -2/d+2 onto the other side, changing it into 2/d+2.

Let the empty side equal zero.
Add 3/d-4 and 2/d+2

Then add that to -3d.

Multiply 0 by d+2 and d-4 to get 2d-2 by itself.
2d=2
d=1
I can't edit the equation, but it's d-4 althroughout the question. Sorry for being so slow.
