Hope this is helpful. Obviously if both teams are -105, then the team totals for both should be 5 if the game total is 10, but if the favorite is -xxx to -xxx, then the corresponding team totals should be 6 and 4. Similarly, from -xxx to -xxx the team totals should be 7 and 3. Does this make sense? I don't know what those lines would be, but if there is a way to figure it out, then you can find discrepancies when comparing team totals with game totals, when factoring in the line. Three dimensions here: team total, game total and line.
