Answer:
Yes
Step-by-step explanation:
The given relation is [tex]x+y=3x[/tex].
We subtract x from both sides to get: [tex]y=3x-x[/tex]
This simplifies to [tex]y=2x[/tex]
The graph of this relation is a straight line that goes through the origin with slope 2.
The graph of this relation passes the vertical line test.
We can rewrite this as [tex]y(x)=2x[/tex]
Therefore the relation [tex]x+y=3x[/tex] represents y as a function of x.
