I got an absolute zero graph with an m= 0.00294 ± 7.6 ×〖10〗^(-6) and b= -276 ± 0.68. but at absolute temperature when the pressure is zero, i tried to solve for the Absolute value (-b/m) but the number is too big...i think it would at least be near to -273˚C??? help the graph was from my physics lab report??? what shape an absolute zero graph should have?

I got an absolute zero graph with an m= 0.00294 ± 7.6 ×〖10〗^(-6) and b= -276 ± 0.68.  but at absolute temperature when the pressure is zero, i tried to solve for the Absolute value (-b/m) but the number is too big...i think it would at least be near to -273˚C??? help the graph was from my physics lab report??? what shape an absolute zero graph should have?

-276 is pretty close to -273. every experiment will have variations that are sometimes unavoidable. as long as your experimental value is less than 10% off of the expected value, we usually consider that a success
