Systems of Linear Equations

1. InterActivity/Simulation/Animation for Boats in the River Problems WindCurrent.gif

  • Set the speed of the current, the speed of the boat in still water and the direction of the boat (downstream/upstream) and see what happens. Relate this to the system of two linear equations in two unknowns. LFS
  === Now a complete interactivity with student handouts and teacher guides with answers!===

2. Graphing InterActivity for Understanding 2x2 Systems

  • Move the points that determine the lines to get a new system and intersection point. Check using your algebra. LFS
