Need help finding the slope of each and also #1 abs #2 below please.

Questions: 1. Examine the 4 V-I plots and indicate if they appear to show a linear relationship between V and I. 2. Which of your resistors has the least resistance to the flow of current as shown by the slope of the plots?Data Table No. 1 No. 2 No. 3 No. 4 10 m 10 m 20 m 20 m 22 AWG 28 AWG 22 AWG 28 AWG V V V I V I O O 0. 04 O 0 . 1 0 . 2 0. 09 6 . 1 0.02 0 . 04 0. 2 0, 37 0.) 0. 2 6.18 0 .04 0. 3 0.53 0.3 1.14 6.3 6. 27 6.3 10.07 0. 15 6.4 0. 78 6.4 0 .4 10.36 0.4 6.09 6. 5 10. 88 0.5 6.5 10. 44 6.5 1 0. 1 2 Slope Slope Slope Slope AV/AI AV/AI AV/AI AV / AI
