Dear Student'

For a metal as temperature increases resistanceR increases 

R =V/I    if you take V on x axis and I on Y axis R is the slope of teh plot

So fpr a metal ar temperature increases R increases ==> 1/ R decreases -->  Slopr of teh plot decreases.

It will be opposit for temperature decrease
