Explanation Result used: In a system of linear equations, the graph of each equation is a line. A system of two linear equations containing two variables has two lines. The graphs of the two lines can appear in one of the three ways. 1. Intersect: If the lines intersect, the system has one solution which is the point of intersection. The system is then said to be consistent and the equations in the system are independent. 2. Parallel: If the lines are parallel, the system has no solution as the lines never intersect. The system is then said to be inconsistent and the equations in the system are independent. 3. Coincident: If the lines lie on top of each other, the system has infinitely many solutions and the solution set is the set of all points on the line. The system is then said to be consistent and the equations in the system are dependent. Calculation: The given system of equations is { − 2 x + y = 4 2 x + y = 0
