Youtube videos by Julie Harland are organized at http://YourMathGal.com.
This collection of videos provides many examples solving non-linear systems of equations (problems where the exponent on a variable is 2), where the solutions show the points of intersection of the graphs. Most problems are shown using the substitution or ellimination method, as well as showing the graphical representation.
