It's common to show the betting lines with each outcome you can bet on followed by a number. In American odds format, it will look something like this:
Team 1 wins: +150
Team 2 wins: -170
In this example, Team 2 is the favorite, and those who bet on it stand to receive only $100 in winnings for every $170 bet. Team 1, on the other hand, is the underdog. For each $100 bet on Team 1, the winning bettors will collect $150 in profits.
There are other ways to display the lines, such as Decimal and Fractional view. You can choose your preferred odds display in the settings menu at your sportsbook.
