Opposite direction + constant proportion ⇒\Rightarrow all points on a falling straight line ⇒\Rightarrow perfect negative correlation (r=−1r=-1).

If XX and YY change in opposite directions (one rises as the other falls) and always in the same fixed proportion, then YY is an exact decreasing linear function of XX. Every observation lies precisely on …
