For those who don't know, the term "affine" means "allowing for or preserving parallel relationships".

I was confused by the word of "affine" before. Later I interpreted it as a translation from a vector that passes through (0,0).

I agree these definitions are confusing. I recall learning about affine functions in eecs16a (see the end of page 5 in https://inst.eecs.berkeley.edu/~eecs16a/sp21/lecture/Note1A.pdf). it seems that while something(eg a line) can be affine, not all of them are linear - the misusage of these definitions in informal conversations is quite common

here, it seems like the translation directly maps to the w-coordinates -- are there cases where this is not true?
