Boyle's law defined at a constant temperature for given amount of an ideal gas.

According to this law, pressure is inversely related to volume under above conditions.

$P = \dfrac{k}{V}$

In the above equation $k = nRT$ and it is the slope the curve formed by $Pvs1 / V$. Hence, more the slope, more is the temperature.
