I'm speculating but I believe it is because the idea was for the -.86..answer( I think I remember that as the start of that one) to be correct, but the wording in the question would not be a relationship between x/y it would be -x/y
so, there is a correct answer, but the positive r value, but someone goofed and made it the negative when they made the key
this is worded poorly, I hope you can see what I mean
