Substitute the *[tex \LARGE x] of one of the ordered pairs for *[tex \LARGE x] in each of the equations.  Substitute the *[tex \LARGE y] value of that same ordered pair for *[tex \LARGE y] in each of the equations.  If the result is two true statements, then the ordered pair is a solution of the system.  Repeat for each of the other ordered pairs.  One of them is a solution, and the others are not.
