Solving Simultaneous Equations Graphically (Maths GCSE Higher and Foundation) 

Practise questions here: mathskitchen.c...
This video goes through everything you need to revise and prepare for your Maths GCSE to do with solving simultaneous equations graphically. If you are doing the Foundation paper you only need to practise the first two questions where the graphs are linear (straight line).
The timings for each of the questions are as follows:
0:42 Q1 Use a graphical approach to solve the simultaneous equations y=2x and y=0.8x+2 (the lines are drawn for you)
2:51 Q2 Draw suitable lines to solve the simultaneous equations y=5x-3 and y=2x+1
4:54 Q3 Use a graphical approach to find solutions to the simultaneous equations y=x²-4x+3 and y=2x-5 (The lines are drawn for you)
5:45 Q4 By drawing a suitable line use the graph to find solutions to the simultaneous equations y=x²-6x+8 and y=x-2
