Graphed Linear and Non-Linear Simultaneous Equations - Graphing Lines and Parabolas

Описание: This lesson includes both linear equations as well as quadratic equations. It assumes previous knowledge of algebraic solutions to simultaneous equations, and graphing lines.

If you have not seen simultaneous equations before or are not confident with graphing straight lines from their gradients and y-intercepts, you may want to see these lessons before starting this one.
