Assume a linear correlation exists. x 3 4 5 5 6 7 y 9 8 5 4 4 4 The equation of the regression line is: Choose between the following A. y = 12.67 – 1.40x B. y = 1.40 + 12.67x C. y = 1.40 – 12.67 x D. y 12.67 + 1.40x Answer by solver91311(16897)   (Show Source): You can put this solution on YOUR website! Showing you how to do a linear regression analysis is a lot of work. Drop me a line and we can negotiate a price. As for this question, I can tell you how to answer just by plotting the points and making an eye-ball trend line. If you plot the points and just make a rough guess at the trend line you will see that the line trends down left to right. That means the equation has a negative slope. Throw out answers B and D which have positive coefficients on x. Of the other two answers, you have a slope of more than -12 and a slope of about -1 and a half. A slope of -12 is very steep, and a slope of -1 is a 45 degree angle. Hence, answer A. John
