Linear function
Linear function (affine form and linear mapping)
A linear function commonly means a straight-line rule y = mx + b in elementary math; in higher mathematics it denotes a linear map preserving addition and scalar multiplication.
Linear independence
Linear independence describes when vectors (or functions) in a vector space cannot be expressed as nontrivial linear combinations of each other; it underlies bases, dimension, and
