its 1.0, right?
the idea is to draw a line through all of the points (as best as you can)
if the points all fall on the line, you have perfect correlation i.e. 1
as you can see, you can't draw a line through your points.
there is a complicated algorithm to compute the correlation
but based on the dots being all over the place I would go with a small number (correlations are between -1 and 1)
