Question 210733
Describe a situation when solving a system of two equations in two variables using the Graphical Method may not be appropriate for finding the precise numerical solution. 
------------------------------------------
0.0000331x - 0.0000000042 = 0.1
-23x + 57 y = 0.0000000000001
---------------------------------
This would be a bit difficult to work with the graphical method.
