In a study designed to predict blood cholesterol levels from the amount of daily saturated fat in grams (X1) and the number of hours of daily exercise (X2) we determine that the slope of X1 is 4, the slope of X2 is 6 and the y-intercept is 170. Which of the following is the regression equation for this data?

A.Y = 170 + 4(X1) + 6(X2)
B.Y = 170 + 4(X1) 6(X2)
C.Y = 170 + 2(X)

D.Y = 170 - 4(X1) 6(X2)
