    Parallel: They have the same slope but different y intercepts.

    Use equation editor in Microsoft Word.

    Why not learn to post in symbols? You can use LaTeX tags

    [tex] \left\lfloor x \right\rfloor \;\& \,\left\lceil x \right\rceil [/tex] gives  \left\lfloor x \right\rfloor \;\& \,\left\lceil x \right\rceil

    [tex] \cup [/tex] gives  \cup is union
    [tex] \cap [/tex] gives  \cap is intersection
    [tex] \subseteq [/tex] gives  \subseteq is subset
    [tex] \cup [/tex] gives  \cup is union
    [tex] \in [/tex] gives  \in is element
    [tex] \emptyset [/tex] gives  \emptyset is emptyset
    [tex] \wedge [/tex] gives  \wedge is or
    [tex] \vee [/tex] gives  \vee is and
    [tex] \sqrt{x+1} [/tex] gives  \sqrt{x+1}

    State the relationship between
    Y=-1/3 x+2 and Y=-1/3 x-2
    Write them as y1= (-1/3)x+ 2 and y2= (-1/3)x- 2. Then y1- y2= 2+ 2= 4. That is, for each value of x, one y value is 4 larger than the other- in terms of the graphs, one line is 4 place higher than the other (so, of course, they are parallel).

    That is essentially what dwsmith is saying.
