Use Graphs to Find or Estimate Solution to Pairs of Simultaneous Two Variable Linear Equations
Standard 8.EE.8 Analyze and solve pairs of simultaneous linear equations graphically. b. Use graphs to find or estimate the solution to a pair of two simultaneous linear equations in two variables. Equations should include all three solution types: one solution, no solution, and infinitely many solutions. Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.
