Please help me solve this! I can do part a, my equations were:

i) xy' + y - 2x = 0

ii) y' (x² - y²) = 2xy

I don't know if these are correct, but I'm having trouble sketching them for part b!

Each equation below defines a one-parameter family of curves. The parameter k assumes all real values. my=m+ (ii) Mar? + w = 2y (a) Derive the DE that is satisfied by the family of curves. State whether the DE is separable, linear or neither. (b) Use information deduced from the DE and from the given equation to give a qualitative sketch of each family. For (ii) consider completing the square
