Which statement best describes the association between variable x and variable y?
a. perfect negative association
b. perfect positive association
c. moderate negative association
d. moderate positive association

Option A. perfect negative association.

Step-by-step explanation:

We take two points lying on the line representing the best relationship between variables X and Y.

Points are (1, 9) and (2, 8), so the slope will be =

Slope of (-1) shows the negative relationship between X and Y which may be represented by Y = (- X), equation of a line.

Therefore, association between variables X and Y can be best described as Option A. perfect negative association
