Quizplus · Accepted Answer

The estimated regression line equation is represented by the format y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope, and b is the y-intercept. In Equation C, the y-intercept is the closest to the origin, and therefore provides the best estimate for the regression line. Equations A, B, and D have y-intercepts that are further away from the origin, indicating that they would not provide as accurate of an estimate for the regression line.
