Section 1.3 Consistent Systems with Infinitely Many Solutions Geometric Representations of 2X2 linear systems (2 lines): • One intersection point • No intersection (parallel lines) • Infinitely many points in common (coinciding lines) The same three possibilities occur with 3X3 systems, there's either one solution, no solution or infinitely many solutions. If we had 3 planes, they could • intersect in one point (one solution) • be parallel (no solution) • coincide (infinitely many solutions) • intersect in a line (infinitely many solutions). Example of a 2X2 system: xx+= 23 1 2 24x1 2 If we use Gauss-Jordan Elimination to solve, 3 123 RR−2
