6xy=13
y=13/6x
You may be confused at this point because your graphing calculator graphs a line when you plug in this equation.
What your calculator is doing is (13/6)x=y which is indeed a line.
However, you are working on inverse variations.
Plug this into your calculator
y=13/(6x)
How is that different?
Just look at the graph.

No, it equals -2xy. lrn2math
The figures are exactly the same, but every point on the first graph is exactly 13 below the corresponding point on the second one.
If that's +6xy, the answer is 2x(x + 3y) If that's -6xy, the answer is 2x(x - 3y)
6xy over 105xyz = 2/35z
