ANSWER

The gas equation is given by, PV=nRT

Taking log on both side, logPV=lognRT

By expanding,

logP+logV=log(nRT)

logP=(−1)logV+log(nRT)

When the temperature is constant, mass remains constant hence mole is constant, it means nRT is constant.

So, log(nRT) is constant

logP=(−1)logV+log(nRT)

This equation follows as,Y=Mx+C

Where, y=logP x=logV

c=log(nRT) and m=−1

Here m is the slope of the equation.

So, slope = −1
