I went to the website

click the "correlation coefficient" link

jimthompson5910 (jim_thompson5910):

tell me what it says

jimthompson5910 (jim_thompson5910):

jimthompson5910 (jim_thompson5910):

that's very close to -1 so that mathematically proves the data points are very very close to a straight line

jimthompson5910 (jim_thompson5910):

which also proves a very strong negative linear correlation

jimthompson5910 (jim_thompson5910):
