I have this midterm coming and i got stuck on this question... and a few others.
State the relationship between
Y=-1/3 x+2 and Y=-1/3 x-2
the / Means Fraction here. can someone also tell me how to input a fraction from 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 $\displaystyle \left\lfloor x \right\rfloor \;\& \,\left\lceil x \right\rceil $
[tex] \cup [/tex] gives $\displaystyle \cup $ is union
[tex] \cap [/tex] gives $\displaystyle \cap $ is intersection
[tex] \subseteq [/tex] gives $\displaystyle \subseteq $ is subset
[tex] \cup [/tex] gives $\displaystyle \cup $ is union
[tex] \in [/tex] gives $\displaystyle \in $ is element
[tex] \emptyset [/tex] gives $\displaystyle \emptyset $ is emptyset
[tex] \wedge [/tex] gives $\displaystyle \wedge $ is or
[tex] \vee [/tex] gives $\displaystyle \vee $ is and
[tex] \sqrt{x+1} [/tex] gives $\displaystyle \sqrt{x+1} $
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.
