Expert Answer:

Slope of I-V graph gives the reciprocal of the resistance.Slope of R2 is larger than that of R1.
begin mathsize 14px style We space know space that space resistance comma space straight R equals straight V over straight I straight L ine space straight R subscript 2 space is space steeper space than space straight R subscript 1 space but comma Slope space of space the space graph space given space will space be space ΔI over ΔV equals 1 over straight R This space indicates space that space resistance space of space straight R subscript 1 space is space greater space than space straight R subscript 2 space end style
