    3 (y - 2) + 6 (x + 1) - 2 = 0

    3y - 6 + 6x + 6 - 2 = 0

    3y + 6x - 2 = 0

    3y = - 6x + 2

    y = - 2x + 2/3

    slope = - 2, y intercept = 2/3

    You can try to convert to y=mx+b form

    m=slope

    b=yint

    solve for y

    first distribute

    3y-6+6x+6-2=0

    3y+6x+6-6-2=0

    3y+6x-2=0

    add 2 to both sides

    3y+6x=2

    minus 6x both sides

    3y=-6x+2

    divide both sides by 3

    y=-2x+2/3

    y=mx+b

    slope is - 2 and yint is 2/3
