Something like the below could work. What it does is, loops through your file line at a time and uses an IF statement to test if it meets the requirements. Then once you find the line, return it or do what you want with it and then exit the for loop if found.

For Each line As String In File.ReadLines("file.txt")
    If line.Contains("Here put the first number") AndAlso line.Contains("Here put the second number")
          'you found the line, now return the line
           Exit For 'Once you found the line exit the loop, as it will continue reading the file
    End If

Also this information could have found by googling how to read in a file. File.ReadLines This link can help you understand whats happening.
