I know for a fact that my attempt is fully wrong, but I am just grasping at straws here and have no clue how to approach this problem. Any help getting me to wrap my head around how to approach this is much appreciated. Thank you in advance.
Thank you so much Ray! I don't know how that didn't cross my mind. I successfully solved the problem now.Try setting f(x,y)=ax+by+cf(x,y)=ax+by+cf(x,y) = ax + by + c for some unknown constants a,b,c.a,b,c.a,b,c. Using your given contitions you can eventually determine a,ca,ca,c and ccc.
