A function, that when applied to consecutive whole numbers, generates a sequence with a constant difference between consecutive terms (Lesson 1 4)
A function of the form f(x) = mx + b where m and b are some fixed numbers The names "m" and "b" are traditional Functions of this kind are called "linear" because their graphs are straight lines (cfLinear Functions)
A function f given by a formula of the type f(x) = ax + b, where a and b are specific numbers
