What does the point at which your curve crosses the horizontal axis represent?
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?
What type of curve? As in what are you graphing..? It's impossible to tell without that bit of info! :)

I am graphing temperature vs volume. Temperature-horizontal axis, Volume-vertical axis.
Still difficult to decide on the experiment. Perhaps you could give a little more detail. Is the horizontal temp axis at zero volume?
The point at which a curve crosses the horizontal axis is called the x-intercept. The x-intercept represents the value or values of the independent variable (typically denoted as x) where the curve intersects or crosses the horizontal axis.
To determine the x-intercept of a curve, you can follow these steps:
1. Set the equation of the curve equal to zero, as the horizontal axis is where the y-coordinate is zero.
2. Solve the equation to find the values of x that make the equation true, typically by factoring or using algebraic methods.
3. The resulting values of x represent the x-intercepts of the curve.
For example, consider the equation of a quadratic function: y = ax^2 + bx + c. To find the x-intercepts of this quadratic equation, set y equal to zero: 0 = ax^2 + bx + c. Solve this equation using factoring, the quadratic formula, or other methods to find the specific values of x where the curve intersects the horizontal axis.
