If the regression line has a positive slope (in this case, 0.01), then the variables have a positive association. However, the strength of the correlation cannot be determined solely from the slope of the regression line, so option A cannot be determined with certainty. Option C is also not necessarily true as a linear regression line can be produced even if the relationship between variables is not strictly linear.
