(Reading Shafarevich Vol 1) What is an affine neighborhood?

In algebraic geometry, an affine variety (or, more generally, an affine algebraic set) is defined as the subset of an affine space that is the set of the common zeros of a set of so-called polynomial functions over the affine space. For defining a polynomial function over the affine space, one has to choose an affine frame. Then, a polynomial function is a function such that the image of any point is the value of some multivariate polynomial function of the coordinates of the point.

WebAn affine transformation (or more simply an affinity) is a non-singular linear transformation followed by a translation. I wonder if these are two different concepts, given that one does not require the linear transformation to be non-singular while the other does?
