Which equation represents a proportional relationship? y = 3x y = −3x + 2 y = (1)/(2x) y = 2 (x + (1)/(3) )

Question

Which equation represents a proportional relationship?

y = 3x
y = −3x + 2

`y = (1)/(2x)`

`y = 2 (x + (1)/(3) )`

Answer 1

y=3x hope this helps 

Answer 2

It's the first one. y = 3x
proportional means they are just some multiple of the other.
