Question

How can graphing be applied to solving systems of non-linear equations?

Answer 1

can you tell us what you have tried ?

Answer 2

sure ,it can applied
2-dimension system can be illustrate by two graph ,and ,cross section =solution of system
3-dimension system can reduce to 2-dimension ,and do like them ...
...
for example : purpose is to find solution of
\[x^2+y^2=1\\y=x^2\]
if you plot them together
you will find two point , and those are solution
