Recall what are parallel lines and intersecting lines from earlier classes.

A system of two equations can be classified as follows:

  • If the two lines are parallel, the system is inconsistent, with no solution.
  • f the two lines intersect at one point, the system is consistent and independent, with one solution.
  • If the two lines are the same, the system is consistent and dependent, with infinitely many solutions.
