The least squares regression line of fat gain y on NEA change x therefore has slope. b = = (-0.7786) kg per calorie. To find the y-intercept, we use the fact that the least squares line passes through (: y = a + bx. 2.388 = a + (-0.00344)(324.8) a = 3.505 kg. The equation of the least squares line is: To find the least squares on your calculator:
