Bill and Ted, two teenagers from San Dimas, California

Can anyone point me in the right direction.  This part of my homework deals with payoff matrix and answering the information listed below. 

Bill and Ted, two teenagers from San Dimas, California, are playing the game of chicken. Bill drives south on a one-lane road and Ted drives north along the same road. Each has two strategies: Stay or Swerve. If one player chooses Swerve he looses face; if both Swerve, they both loose face. If both choose Stay, they are both killed. Consider the following payoff matrix:
