    Parallel.

    Step-by-step explanation:

    We need to convert the 2 equations to slope-intercept form (in bold) : -

    2x + y = 8

    y = - 2x + 8.

    6x + 3y = 12

    3y = - 6x + 12

    Divide through by 3:

    y = - 2x + 4.

    The slopes are the same (both - 2), so they are parallel.
