What does the point at which your curve crosses the horizontal axis represent?

What type of curve? As in what are you graphing..? It's impossible to tell without that bit of info! :)
Maya,

I am graphing temperature vs volume. Temperaturehorizontal axis, Volumevertical axis.

Still difficult to decide on the experiment. Perhaps you could give a little more detail. Is the horizontal temp axis at zero volume?

so we did a chemistry lab to find the relationship between temperature and volume or charle's law. In the experiment, i got t1v1=372K, 267.2 cm^3
t2v2=277K,169.1 cm^3
so i graphed that
THen they told us to chose 2 other points from that line, TaVa and TbVb and find its K value.
i chose TaVa=200, 70
TbVb=240,110
then k value of TaVa=0.35
K value of TbVb=0.46
Then they asked what does the point at which your curve crosses the horizontal axis represent?
