This is meant to determine which of the three ways we are studying to use when solving a system involving at least one non-linear equation.
                 
Do the two equations have the exact same powers of either x or y?
YES
 Use elimination!
 
 
 

NO







Does ONE of the equations have just x or just y (no squares) in it?
YES
 Use substitution!
 
 
 

NO







Graph them, find the intersections Remember to use both + and - if you have a root!
