Answer: b. This form of analysis estimates the coefficients of the linear equation, involving one or more independent variables that best predict the value of the dependent variable. Because the regression line minimizes the distance between each individual point and the regression line. My very basic solution is just copy the change of b when I predict a, like this: ch = (b[7] / b[6]) - 1 a[7] = a[6] + (a[6]*ch) 2.
