Boyle's Law Chemistry question! ?
If you graph pressure vs. volume and pressure vs. volume^-1, which relationship is linear? Why is only one linear?

Boyle's Law says that at constant temperature, pressure is inversely proportional to volume (P = k/V). That means that as pressure increases, volume decreases. If you take the inverse of the volume (sort of like reading a graph from right to left), then you are basically going to get a line because pressure will be directly proportional to the inverse of volume.
P*V = constant
P = constant/V
Substitute Vi for 1/V and you will see: P = Vi * constant + 0 (y = mx + b)
