Question 570709: The points on a scatterplot lie very close to the line:
y = 6x - 1
The correlation between x and y is closest to which of the following values?
You can put this solution on YOUR website! Correlation is defined to be between -1 and 1, so 6 and -6 are impossible. The correlation is 1 if the (x,y) points all lie on a line of positive slope (-1 for negative slope). Since y = 6x - 1 has positive slope, the correlation is roughly 1.
