The line is used to balance the betting action between two teams or players, often with a point spread or moneyline. In point spread betting, the favorite gives points, and the underdog receives points, while in moneyline betting, the line indicates how much a bettor must wager to win a certain amount, or how much they stand to win by betting on the underdog. The line can shift based on betting activity or other factors like injuries and weather.
Lines Example
For example, in an NFL game, if Team A is a 7-point favorite over Team B, the line would show as “Team A -7,” meaning Team A must win by more than 7 points for a bet on them to win.
