A stand-alone system have different slopes, therefore, has a unique solution.If two lines have the same slope, then they are incompatible. The reason is that the two lines may have NO SOLUTION or an infinite number of solutions.An inconsistent system that has an infinite amount of solution is said to be dependent.Now let's make the subject in both equations, to obtain,For the seccond equation, we haveWow, the two systems have the same slope and intercept. This means that the system has infinitely many solutions, therefore it is dependent.The two systems are dependent
