The aim of this study is to clarify characteristics of a functional view into the liner equation with two unknowns in textbook. For the aim of this study, we theoretically analyzed an activity that students must transform the view of the liner equation in textbook; from “equality” to a “functional relationship”. As a result, this paper identified two way of functional view into the liner equation. And a new hypothesis was caused from the result of analysis in this paper.
