a triangle is drawn on the coordinate plane. it is translated 4 units right and 3 units down. which rule describes the
translation?
(x, y) → (x + 3, y - 4)
(x, y) — (x + 3, y + 4)
(x, y) - (x + 4, -3)
(x, y) → (x + 4, y + 3)

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.
