What determines the position of the lines dividing the bottom square? |
Graphical solution of simultaneous equations
|
1. Rearrange the equations into the form y = mx + c 2. Think where those lines are on the grid 3. Move the Point P to where you think the lines cross each other 4. Reveal the lines and distance from P to I 5. Record the solution and distance for each question |

Can you keep your distance reducing? Can you get an average distance below 2 or 1 even? Can you make up a set of simultaneous equations that have no solution? |
