Explain how you can determine whether a system of two linear equations will be consisten, dependent, or inconsistent?

  • Math -

    consistent if their slopes are different
    x+y=5
    2x-3y=6

    dependent if one equation is a multiple of the other.
    2x+3y=9
    4x+6y=18

    inconsistent if the slopes are the same, but one equation is not a multiple of the other.

    3x-y=8
    9x-3y=5
