 # Systems of Linear and Quadratic Equations

Videos and lessons to help High School students learn how to solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. For example, find the points of intersection between the line y = -3x and the circle x2 + y2 = 3.

### Suggested Learning Targets

• Solve a system containing a linear equation and a quadratic equation in two variables (conic sections possible) graphically and symbolically.
