    put the problem in slope intercept form (y = mx + b) with m being the slope and b being the y intercept.


    3x + y = 8

    y = -3x + 8
    y = mx + b


    so m = ?

    and b = ?

    yes for the y-intercept, what about the slope?

    The slope is 0.

    Thank you for the help.

    Actually rhe slope is -3.

    y = mx + b

    where m is the slope and b is the y intercept.

    so,

    y = (-3)x + 8
    y = (m )x + b
