No, it equals -2xy. lrn2math
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.
If that's +6xy, the answer is 2x(x + 3y) If that's -6xy, the answer is 2x(x - 3y)
