Example Worksheet: Linear Equations

Below you can see two linear equations whose parameters [i]m[/i] and [i]b[/i] can be modified using the corresponding sliders.
Task 1
Explore how the parameters of the linear equations change the corresponding lines in the [img]https://www.geogebra.org/wiki/uploads/thumb/c/c8/Menu_view_graphics.svg/16px-Menu_view_graphics.svg.png[/img] [i]Graphics View[/i] by changing the values of the sliders. 
Task 2
Try to modify the parameters so that the lines intersect at the origin of the coordinate system. How many solutions can you find?
