What you'll learn

  1. Solve a system of two linear equations in two variables using the graphing method (approximately) and interpret the intersection point
  2. Solve a system using the substitution method (exactly) and verify the solution satisfies both equations
  3. Solve a system using the elimination method (exactly), applying the theorem from REI.C.5 to justify each step
  4. Identify the three possible solution types -- one solution (consistent independent), no solution (inconsistent), infinitely many solutions (consistent dependent) -- and explain their geometric meaning
  5. Choose the most efficient method for a given system and apply it correctly
