Explanation:
The line of best fit to a scattergram is obtained in linear regression analysis by minimizing the sum of the squared errors.
For example, in the diagram shown below, there are n data points in the scattergram.
The error for the i-th data point is

.
The coefficients (a and b) for the line of best fit are determined using calculus, to minimize

.
The rationalized form of 1+ √2/1-√2 is -2√2-3
