Is that correlation coefficients? If so:
+1 is perfect positive correlation
0 is no correlation
-1 is perfect negative correlation

So if it's closer to 1, it's a strong +ve correlation etc.

so you know the 0.08 correlation, on the graph it shows a weak positive correlation from the plotted points but obviously the value of 0.08 is negative??

What do you mean? 0 < 0.08, so it is positive?

If the question just asks you to analyse those numbers, then not really.
