A pair of linear equations which has no solution, is called an inconsistent pair of linear equations. A pair of linear equations in two variables, which has a solution, is called a consistent pair of linear equations. A pair of linear equations which are equivalent has infinitely many distinct common solutions. Such a pair is called a dependent pair of linear equations in two variables.
1. The two lines \(2x+y=5\) and \(4x+2y=10\) are
2. The two lines \(3x-5y=20\) and \(6x-10y=40\) has
3. The two lines \(x-2y=8\) and \(5x-10y=10\) are
4. The value of \(m\) if the pair of linear equation \(mx+2y=5\) and \(3x+y=1\) has unique solution
