    well, all the options are linear; is the slope the same between all the data points?

    (h,s) ------- (6,82) -(4,58) -------- (2,24) ; slope = s/h = 24/2 = 12 (10,130) - ( 4, 58) -------- (6 , 72) ; slope = s/h = 72/6 = 12 so its either c or d from that experiment

    lets use (4,58) into the equation of d to check for it :) y=12x+10 58 = 12(4)+10 58 = 48 + 10 58 = 58 ; so (d) works out good
