We may be able to interpolate by connecting our sample of points with a curve. Circles Outline Relations Graphing Relations Examples Example Graph the relations. (2000, 6071 M), (2005, 6454 M), (2010, 6877 M), (2012, 7035 M). Birthdays to month. Month Birthdays y x 1 0 2 4 3 0 4 1 5 4 6 2 y = 3x + 1.
