Hi

x	y     (x-4.25)   (y-12.75)    Product (  x-4.25)^2

2	7	-2.25	-5.75	12.9375	5.0625

4	11	-0.25	-1.75	0.4375	0.0625

5	13	0.75	0.25	0.1875	0.5625

6	20	1.75	7.25	12.6875	3.0625

17	51	0	0	26.25	8.75

4.25	12.75				



y = ax + b

a = 26.25/8.75 = 3

b = m%5By%5D+-+a%2Am%5Bx%5D

b = 12.75 - 3(4.25) = 0

y = 3x is the Regression Line
