Key Concepts:
- Intersection Points: Solutions to systems occur where two graphs meet.
- Parabolas and Lines: Quadratic equations form parabolas; linear equations form straight lines.
Skills Covered:
- Determining solutions by analyzing graphs
- Identifying when no solution exists based on graph intersections
Example Problems:
- Given the graphs of (y = x^2 - 4x + 3) and (y = 2x - 1), find their intersection points.
- Determine the number of intersection points of the graphs of (y = x^2 + 3x + 2) and (y = - x - 2).
