How can I tell the differance between a Hatchback and a Fastback, I've gotten into many arguements about it, and I don't know what I have. the rear looks like a slope, but not like a minivan, can someone just tell me what a hatch(or fast)back looks like?

 

this is what the fastback (hatchback) looks like



this is the trunk back or coupe

 

Hatchback=Fastback

Fastback=Hatchback
