Graphical solution of simultaneous equations

Topic:
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?
