Okay. This follows your last question a bit. First, is the coefficient going to be positive or negative?

OpenStudy (ttp):

negative?

OpenStudy (anonymous):

Yes! Because the points are going generally from the top left to the bottom right. A positive one would be going from the bottom left to the top right.

OpenStudy (anonymous):

Now, you have to determine the number. The higher the number, the more closely packed the points are. That is, the more they resemble a line if you were to connect them.

OpenStudy (anonymous):

So a coefficient of -.9 would be for a graph with points that generally form a line.

OpenStudy (anonymous):

A coefficient of -.6 would be still sort of close to a line, but the points are a little more spread out. What does that graph look like to you?

OpenStudy (ttp):

option?

OpenStudy (ttp):

c?

OpenStudy (anonymous):

Not exactly. You said yourself that the coefficient would be negative. Option C is positive. Try again.

OpenStudy (ttp):

option b than

Correct! Because it's negative and matches up with how close the points are to a line, which is kind of close, but not enough to be -.9
