Abstract: In Grade 10 Geometry, chapter III “Coordinate methods in Plan” in general, and lesson “Parametric equations of straight lines” in particular, is presented as mathematical tools to
solve mathematical problems internally. Integrated teaching is a solution to help students develop the ability to solve problems in learning and real life. The parametric equations of straight lines
are also included in Grade 10 Physics, expressed through the concept of equations of uniform linear motion of a point, hence chosen as the object of teaching in the light of Math - Physics
integrating interdisciplinarity. This study focuses only on the relationship between the parametric equations of straight lines in mathematics and the equations of uniform linear motion in physics.
Keywords: uniform linear motion, straight line, GeoGebra, parametric equation, integrated.
