E) none of these answer options are correct.

Question

Quizplus · Accepted Answer

The slope of a regression line is calculated by dividing the change in vertical distance (the dependent variable) by the change in horizontal distance (the independent variable). This is also known as the rise over run. Option A is incorrect because the intercept is not involved in calculating the slope. Option B is incorrect because it has the numerator and denominator reversed. Option C is incorrect because the intercept term is not involved in calculating the slope.
