Question 35958
the question is tell wether x and y show direct variation,inverse variation or neither 

1.y=3x  
Direct because as x increases, y increases.
Try it with x=2 and x=4.

2.y=2/x
Indirect because as x increases, y decreases
Try it with x=2 and x=4 

3.x+y=7 
While it is true that y decreases as x increases this
equation is not described as indirect variation.  It
is neither.

 4.xy=5
Indirect
