    In order for us to know whether the equations are consistent, independent, coincident and inconsistent according to their slope.

    1. 4x+y=8 - - - > y = - 4x + 8 - - - > m = - 4

    x+3y=8 - - - > y = - 1/3x + 8/3 - - - > m = - 1/4

    Independent

    2. - 4x+6y=-2 - - - > y = 3/2x - 1/3 - - - > m = 3/2

    2x-3y=1 - - - > y = 3/2x - 1/2 - - - > m = 3/2

    Inconsistent

    3. 5x-2y=4 - - - > y = 5/2x - 2 - - - > m = 5/2

    5x-2y=6 - - - > y = 5/2x - 3 - - - > m = 5/2

    Inconsistent

    4. y=3x-4 - - - > y = 3x - 4 - - - > m = 3

    -3x+y=-2 - - - > y = 3x - 2 - - - > m = 3

    Inconsistent
