Find the equation of the regression line
(Round the constant two decimal places as needed. Round the coofficient to three decimal places as needed.)
Identify a characteristic of the data that is ignored by the regression line
A. There is no characteristic of the data that is ignored by the regression lino.
B. There is an influential point that strongly affects the graph of the regression line,
C. The data has a pattern that is not a straight line,
OD. There is no trend in the data
