Then how come if I find some other point that lies on the line \(x+y=3\) such as \((8,-5)\), that would be a negative number when plugged into \(x^2y\)? Wouldn't mean that \((0,3)\) isn't actually the minimum? Maybe I am misunderstanding the way these work, but if somebody could explain this to me that would be nice. Thanks
