    8x + 2y = 21

    8x - 8x + 2y = - 8x + 21

    2y = - 8x + 21

    2 2

    y = - 4x + 10.5

    Slope: - 4

    2y+8x=21

    This is in standard form, lets convert to slope intercept form

    slope intercept form : y = mx + b

    2y + 8x = 21

    -8x - 8x

    2y = - 8x + 21

    y = - 4x + 21/2

    Answer: m = - 4
