Abstract	Resumo: A proposta do presente artigo e apresentar e discutir os resultados de uma pesquisa de trabalho de conclusao de curso realizada em 2014. Atraves de uma revisao bibliografica inicial, verificou-se que a forma na qual tradicionalmente se apresenta o conteudo de Sistemas Lineares 2x2 prioriza o tratamento algebrico, e o estudo da interpretacao grafica da solucao acaba por ser insatisfatorio ou inexistente. Este trabalho fundamenta-se na teoria de representacoes semioticas de Raymond Duval, uma vez que nossa hipotese e a de que a mudanca no tratamento dos registros internos de representacao contribui e catalisa o processo de aprendizagem. Na tentativa de verificar essa hipotese, propoe-se uma sequencia de atividades organizada em dois momentos: um momento inicial, em que nao se faz uso de recursos tecnologicos, e um segundo momento em que se faz. Buscou-se com o uso do software GeoGebra tornar o processo dinâmico e interativo, facilitando a construcao do conhecimento pelo proprio estudante. Os dados analisados, obtidos a partir do material produzido pelos estudantes, revelam que o recurso tecnologico utilizado no decorrer das atividades produz um efeito positivo na construcao e aprendizagem dos conceitos matematicos discutidos na abordagem envolvendo Sistemas Lineares 2x2. Palavras-chave: Sistemas Lineares. Tecnologia. Representacoes Semioticas. Registros de Representacao. EXISTENCE OF SOLUTIONS FOR LINEAR SYSTEMS 2X2: A CASE STUDY INVOLVING THE USE OF DIGITAL TECHNOLOGY WITH HIGH SCHOOL STUDENTS Abstract: The purpose of this paper is to present and discuss the results of an end course work survey, conducted in 2014. Through an initial literature review, it was found that the form in which content has traditionally been Linear Algebraic Systems 2x2 prioritizes the treatment and study of graphical interpretation of the solution turns out to be unsatisfactory or nonexistent. This work is based on the theory of semiotic representations of Raymond Duval, since our hypothesis is that the change in the treatment of representation registers contributes and catalyzes the learning process. In an attempt to verify our hypothesis, we propose a sequence of activities organized in two phases: in a first moment does not make use of technological resources and the second time yes. We attempted to use the software GeoGebra make the dynamic and interactive process, facilitating the construction of knowledge by the student himself. The analyzed data obtained from the material produced by the students reveal that technological resource used in the course of activities has a positive effect in building and learning of mathematical concepts discussed in approach involving Linear Systems 2x2. Keywords: Linear Systems. Technology. Semiotics representations. Representation records.
