HI iv'e been trying to solve this problem for far too

long, and tried a bunch of stuff, TBH im not sure exactly what its asking for, I think it wants me to find a function where the tangent line of the given function is true for that graph. Ive found the implicit differentiation to come to dy/dx = -10x/18y as far as taking the derivative goes its dead easy, but Im not sure where to go from here, ive tried finding points on the graph of of the original function and using the implicit differentiation as the slope, use point slope formula to get a function that is true for the graph, but that doesn't work, and you cant go the easy route of finding an x intercept and solving for the derivative, because the original function is undefined for all x=0
