R is partly constant and partly varies with E when R=530,E=16000 and when R=730,E=3600.
i)find the formula which connects R&E
i)find R when E=1300.

1. R = mE + b
case1: R = 530, E = 16000
530 = 16000m + b **
case2: R = 730, E = 3600
730 = 3600m + b ***

subtract *** from **
-200 = 12400m
m = -1/62
back in ***
3600(-1/62) + b = 730
b = 24430/31

R = (-1/62)E + 24430/31

so when E = 1300
R = (-1/62) + 24230/31
= 23780/31 or appr 767
