B) = -0.85 X + 20.93 
C) = 20.93 X + 0.85 
D) = 0.85 X + 20.93

Quizplus · Accepted Answer

The regression equation is in the form of Y = aX + b, where Y is the dependent variable and X is the independent variable. Looking at the answer choices, only option B has the correct format of the equation with -0.85 as the slope and 20.93 as the y-intercept. Option A has an error in the ID number, and option C and D have the wrong sign for the slope or intercept. Therefore, option B is the best choice for the regression equation.
