A system of linear equations is dependent if it is a consistent system that has an endless or infinite number of solutions. This means that both equations represent the same line when plotted on a graph. A dependent system of equations has infinite solutions. In contrast, an independent system of equations has exactly one solution. A system of equations is called inconsistent if there is no solution because the lines are parallel. A dependent system of equations occurs when the same line is written in two different forms so that there are infinite solutions.
