4-16.

Jack and Jill are playing the Mystery Game. Remember that having four tiles of the same color in a row, column, or diagonal wins the game. List the coordinates of the points that they have already played, as shown below. Give two more points, one to Jack and one to Jill, so that either one might win.

Remember that an ordered pair is (x, y).

Some of the points that Jack and Jill could use to win are shown at right.

Can you find others? Remember to name the ordered pairs!
