40 points geometry - when you know the scale factor (e. g. 3), why does the point of dilation matter? wouldn't each coordinate be multiplied by the scale factor no matter where it was dilated? (e. g. 3, 6 becomes 9, 12) or am i missing something?

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
