Lesson details
Lesson outcome
I can solve two linear simultaneous equations graphically (0 or 1 or infinitely many solutions).
Show transcript
You can use your knowledge of linear graphs to draw the graphs of both equations on the same axes.
If there exists a solution, the point of intersection is that solution.
If the lines are parallel then there are no solutions.
If the lines lie on top of each other, there are infinitely many solutions.
