Beatrice calculated the slope between two pairs of points. She found that the slope between (-3, -2) and (1, 0) is ž.
She also found that the slope between (-2, -1) and (4, 2) is .
Beatrice concluded that all of these points are on the same line.

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.

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.
