How am I supposed to graph the inverse variation y = 2x? Which values should I use?

Okay, you need to rewrite it in standard form.

y−2x=0

You would need the X and Y intercepts.

x-intercept: (0,0)
y-intercept: (0,0)

Then the slope
(m) is slope
m=2

Here is the points you need
(0,0),(1,2)

Now you just need to put in on a actual graph. I can't do that part for you.

Understood now? :)
