Systems of Linear Equations · Algebraic Thinking

Graphical Solutions to Systems

Finding the intersection of two lines and understanding it as the shared solution to both equations.

Key Questions

  1. 1What does the point of intersection tell us about two competing service plans?
  2. 2Why do parallel lines represent a system with no solution?
  3. 3How does graphing help us estimate solutions that are not whole numbers?
