Solve the system of equations by graphing. Then classify the system.x+y=8x-y=-2

  • Math -

    I assume you have

    x+y = -2
    8x - y = -2

    solve by graphing??
    (perhaps to show the concept)
    Just add them
    9x = -4
    x = -4/9

    then -4/9+y=-2
    y = -14/9

    (I doubt if you could have obtained that exact value by looking at a graph)
