Proportional Relationships and Equations: Grade 7 Practice

① This GeoGebra example is a practice activity for Grade 7 mathematics on 'Proportional Relationships and Equations', designed to help students visually grasp how proportional relationships translate into linear equations. ② Core math concepts include ratio, direct proportion, linear equations, correspondence between variables, and representing the constant of proportionality graphically. ③ Construction highlights: Based on the summary, it uses several point objects (A1, B1, A2, A3, A5, B4) likely placed on a coordinate grid to mark paired values of a proportional relationship; by dragging points or observing coordinates, students explore the constant k and the equation y=kx. No advanced commands are involved, making it a basic blend of geometry and algebra. ④ Suitable for Grade 7 students as classroom practice or homework, and for teachers to demonstrate proportional relationships visually, bridging concrete graphs and abstract equations.
