    The objective of this research was to determine the extent to which the use of the GeoGebra tool influences the understanding of the linear function in ninth grade students of the Colegio Nuestra Señora de la Candelaria in Cimitarra Santander. The study was framed in an experimental design of quasi-experimental level. We worked with a population of 138 students of ninth grade, of which 70 students were selected as sample, so that an experimental group was established (formed by the ninth grade "C", with 36 students, who interacted with the digital tool GeoGebra) and a control group (Ninth Grade "A" with 34 students that was used as a witness), which were selected naturally as constituted in the institution. A pre-test was applied to the two groups in order to take a baseline and use it as a reference. Then the two groups were subjected for 13 sessions to the study of the linear function, with the difference that the experimental group (9ºC) was exposed to the influence of the GeoGebra digital tool and the control group to the traditional methodology, to develop this theme. Finally, a knowledge test on the aforementioned subject was applied again, in order to verify the fulfillment of the objectives and to check or reject the hypotheses. As a result, it was obtained that 100% of the students in the experimental group passed the test with a grade equal to or higher than 55 points, the average of this group was 78.19, which turned out to be 22.9 points higher than that obtained by the group. control that was of 55.29 and in addition half of the experimental group obtained notes superior to 80; 25 points more than the control group in this same indicator that was 55. It was evident that the continuous exposure to the digital tool Geogebra allowed to understand the concept and the different forms of expression of the linear function and were able to solve problems of their school environment , on this subject in a more easy and practical way.
