Is y=9x direct or inverse variation

Step-by-step explanation:

Explanation:

y

x

=

9

=> multiply both sides by  

x

:

y

=

9

x

=> in the form of  

y

=

k

x

=>  

y

varies directly as  

x

,

where:  

k

is the constant of variation.

Thus in this case:

y

=

9

x

=>  

y

varies directly as  

x

,  

k

=

9
