Summary: The present work aims to show the result of a research whose objective was to produce a manipulable didactic material for blind students, with the potential to (Re)construct the concepts of slope coefficient and linear coefficient of the polynomial function of the 1st degree. The research is qualitative and descriptive, fitting in as applied in nature. For the literature review, we used the legal documents that regulate basic education in Brazil, especially education aimed at people with special educational needs; Brazilian authors who discuss mathematics education from the perspective of inclusive education and those who discuss the teaching of algebra involving blind students. Studies have been carried out on some of Duval's and Radford's ideas on the Theory of Registers of Semiotic Representation, and the development of algebraic thinking, respectively. The evaluation of the MDM was the result of a reflection based on some questions/ideas suggested by Lorenzato in order to achieve the specific objectives: to describe the material produced, as well as its use in the classroom and; assess the strengths and/or limitations of the MDM produced. We conclude that the material produced met the general objective of the research, to have the potential to approach the slope coefficient and the linear coefficient of the affine function, among others it can be X-ray, because the MDM can enable the teacher to verify concepts that need to be reviewed or expanded and the Computer, since the MDM was designed for blind students, Precisely because of their difficulty in being able to "visualize" the construction of the concept of angular and linear coefficients, via certain mathematical software, such as GeoGebra, which still does not have resources to meet the blind student's needs.
