The Linear Function

The Linear Function app helps students and teachers to learn and practice about various properties of the linear function. It provides randomly generated practices for identifying slopes and intersection points, with both algebraic formulation and graphical presentations. It enables the student to understand the interaction of the linear function with the axes as well as with other linear functions by dynamically choosing points, creating lines and presenting intersection points. Furthermore, it presents examples for a full solution of the intersection point between two functions both through the methods of substitution and elimination.
