Answers vary. Students should choose any point that is not on the line of
How is the solution to a system of equations represented on a graph?
It is the point where the graphs of the two equations intersect.
What is the solution to this system?
How can you verify that this ordered pair is correct?
Substitute its values into the two equations you came up with; it should make both equations true.
