@phi

Answer 2

did you plot the points?

Answer 3

then try to draw a line that is "close" to all of the points.

if the points are all close to this line you have high correlation (close to 1)

if the line slopes up (and to the right) you get a positive correlation number
if the line slopes down (and to the right) it is negative.
