What does it mean if a system of equations has no solution?

Back

If a system has no solution, it means the equations represent parallel lines that never intersect.

What does it mean if a system of equations has infinitely many solutions?

Back

If a system has infinitely many solutions, it means the equations represent the same line, and every point on that line is a solution.
