bardock:  please explain in your own words what "y-intercept" means.  Once you've done that, it may be easier for you to answer this question yourself.

anonymous · Answer

i dont even know O.o

agent0smith · Answer

Do you at least know which one is the y axis?

anonymous · Answer

yeah the vertical one

mathmale · Answer

OK, very good.  Now take a look at line A and determine where, on the y-axis, the line crosses the y-axis.  What's the y-value there?

anonymous · Answer

wouldnt it be 9/2?

mathmale · Answer

Bardock:  Please take another look at line A.  Do you see how line A crosses the y-axis just below the x-axis?  Again, I ask you to identify the y-value of the crossover point.  (Too bad the graph's not bigger, as it's a bit hard to read.)

anonymous · Answer

i think it is (0,1/2) if im not mistaken

mathmale · Answer

I like the way you've written that as a point, with the x-coordinate = to 0 and the y-coordinate equal to 1/2.  
Myself, I read the y-coordinate as y = -1.  Want to argue over that?  Seriously, I want you to feel comfortable determining this sort of info from a graph yourself.

agent0smith · Answer

The y is definitely -1, not close to 1/2.

agent0smith · Answer

I think you're finding the slope or something (which isn't 1/2 either) not the y intercept.
