Quizplus · Accepted Answer

The intercept of a regression line is the value of y when x is equal to 0. Since we only have the equation of the regression line and no data points, we cannot find the exact intercept. However, we know that the equation of the line is y = 11ebb61d_fbf1_8bd6_92a9_97c7ea07a6fa_TB8376_11, which means that the intercept is a constant term that is added to the slope. Since the slope is not given, we cannot calculate the intercept exactly, but we know that it will be a positive number since the constant term is positive. Therefore, the best choice is C, 4.6. The intercept of the regression line is the value of y when x=0. Since the equation of the regression line is not provided, we cannot calculate the intercept directly. Therefore, we can only select one of the given options based on the process of elimination. Option C is the only positive value, and since the intercept cannot be negative, it is the best choice.
