a) The red and gren line have the right direction, and, hence, one of them could be the regression line. b) The blue line seems to represent the mean value of the data with respect to y and thus could be the regression line. e) The point in the top right corner has a strong infucnce on the regression line. d) Leaving aside the point in the comer, the red line seems to fit better to the rest of the data.
