If ( x 0, y 0) is the point through which the regression line must pass, fit the model y − y 0 = β ( x − x 0) + ε, i.e., a linear regression with "no intercept" on a translated data set. In R, this might look like lm ( I (y-y0) ~ I (x-x0) + 0). Note the + 0 at the end which indicates to lm that no intercept term should be fit.
