## Graphical Solutions **What are Graphical Solutions?** Graphical solutions involve finding the values of variables that satisfy one or more equations by plotting their graphs and identifying their points of intersection. **Key Points** 1. To solve simultaneous equations graphically, you must plot each equation on the same coordinate plane. 2. Create a table of values for each equation to get eno [Preview only]
