What does it mean if two lines are parallel in a system of linear equations?

Back

The system has no solution because the lines never intersect.

Front

What is the meaning of 'no solution' in a system of linear equations?

Back

It indicates that the equations represent parallel lines that do not intersect.

What is the meaning of 'infinitely many solutions' in a system of linear equations?

Back

It occurs when the equations represent the same line, leading to an infinite number of intersection points.
