Question

A direct 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

Answer 1

It’s the first two answers isn’t it? Because xy=k is inverse

Answer 2

The correct answer is:

• Two variables increase at the same time.
• Two variables decrease at the same time

Step-by-step 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 :

`x\propto y`

`x=ky`

`k=(x)/(y)`

k = Proportionality constant
