Solving Equations Graphically
Solving (simultaneous) equations graphically
- This is a way to solve simultaneous equations (see Simultaneous Equations)
- Coordinates of the intersections are the solutions
How do I solve simultaneous equations using a graph?
- Use graphs and algebra together
- Sketch a graph if it has not been given
- Read/interpret a graph if it has been given
- It can be difficult to tell from a sketch if graphs intersect once, more, or not at all
