Adirect relationship occurs when: two variables increase at the same time two variables decrease at the same time one variable increases as another variable decreases xy=k select all that apply

The correct answer is:

Explanation:

In a direct relationship , two given variables are varying directly two each other. Which can be easily understood by saying if value of one variable is increasing and then the value of the another variable will also increase and vice-versa.

Say two variable x and y :

k = Proportionality constant

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
