The slope of the given graph gives us the inverse of resistance. Resistance of a material increases with increasing temperature because the collision between the molecules increases. 
In the graph given, T2 has a smaller slope and hence corresponds to higher resistance. Therefore, T2 > T1.
i hope this will help you
