You can put this solution on YOUR website!
Graph of Choice A) y/x=5 (note: you have to solve for y first to get y = 5x... x cannot equal 0)

+graph%28+500%2C+500%2C+-10%2C+10%2C+-10%2C+10%2C+0%2C5x%29+

Graph of Choice B) y = 5/x, x cannot equal 0

+graph%28+500%2C+500%2C+-10%2C+10%2C+-10%2C+10%2C+0%2C5%2Fx%29+

Graph of Choice C) y = 13x^2 ... Note: I'm assuming you meant to say "13 x squared"

+graph%28+500%2C+500%2C+-10%2C+10%2C+-10%2C+10%2C+0%2C13x%5E2%29+


====================================================================

B) y=5/x is an inverse variation since it is in the form y+=+k%2Fx (in this case, k = 5)
