Decision Tree: How Many Solutions Does a Pair of Linear Equations Have?

The map in words

  • Start: Write equations in standard form
    • Calculate a1 divided by a2
      • Calculate b1 divided by b2
        • Are the two ratios equal?
          • No: a1/a2 not equal b1/b2: Intersecting Lines
            • Unique Solution - Consistent
          • Yes: a1/a2 equals b1/b2: Calculate c1 divided by c2
            • Is c1/c2 also equal to a1/a2?
              • No: c1/c2 is different: Parallel Lines
                • No Solution - Inconsistent
              • Yes: All three ratios equal: Coincident Lines
                • Infinitely Many Solutions - Dependent Consistent
