Write the equation of the line which is perpendicular to the line y=1/2×-3 and which passes through the point (-2,-5)

Answers

y = -2x - 9

Step-by-step explanation:

The equation given, y = 1/2x -3, is a linear equation. Lines that are perpendicular to linear equations have slopes that are the reciprocal opposite of the given line. Since the slope of the given line is 1/2, the reciprocal opposite is: -2. Now that you have the slope and a point, you can use slope-intercept formula to solve for 'b':

y = mx + b

-5 = -2(-2) + b

-5 = 4 + b

-9 = b

-2 = m

y = -2m - 9

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.
