The elevation of a lake surface (feet above sea level) varies according to the annual flow of a river that feeds it. A geological survey provided the following data from equally spaced intervals of time over a 15 year period. Time Period Elevation 1 2795 2797 3 2797 2798 2802 6 2803 2807 2808 2810 10 2811 11 2812 12 2815 13 2816 14 2817 15 2817 Make a time-series graph displaying the data.
