Needs["Statistics`DataManipulation`"]

list = {{Indeterminate, Indeterminate}, {2, 46.366782627682156`}, {3, 
      69.54492936918818`}, {4, 92.9399378277631`}, {Indeterminate, 
      Indeterminate}, {6, 138.99867008246846`}, {7, 161.99861473742195`}, {8, 
      185.10189757264996`}, {9, 208.72560583731791`}, {10, 
      231.91791443344684`}}

DropNonNumeric[newList]

{{2,46.3668},{3,69.5449},{4,92.9399},{6,138.999},{7,161.999},{8,185.102},{9,
