. Question 11 A multiple regression equation with 2 independent variables has the following properties: For every unit increase in 1, y decreases by 18.9 on average, holding $2 constant. For every unit increase in x2, y increases by 10.6 on average, holding r 1 constant. o When 1 = 0 and x2 = 0, 7 = 70. Which of the following best represents the equation? Oy = 70 - 18.9x1 + 10.6x2 Oy = 70 + 18.9x1 + 10.6:2 Of = 70 -18.9r1 - 10.612 Oy = 18.9x1 + 10.6r2 - 70 Of = 70 + 18.9x1 - 10.6:2
