From research we know that students have difficulty understanding multiple representations of the same information. This app allows students to explore how changes in the formula or graph or table will impact the other two. Another nice feature of the graph is the ability to watch how a change in the scale will not change the formula or table but will change the graph appearance.
The app allows you to enter a linear equation to be displayed on the graph, but you can also use the dots on the line to move it around yourself. You can also choose a different starting point for x in the table.
Linear Model supports equations in both slope intercept, y = mx + b, and standard form, Ax + By = C formats. Enjoy!
