I can determine an inverse relationship and create an equation to describe it. Pun of the day: (Thanksgiving Themed) With a partner, you need a lab paper, a pencil, ruler, tape, and 10 pennies 5. Graph your points (from the table) on a graph with the number of pennies on the x-axis and the distance from the fulcrum on the y-axis. Then draw a smooth curve through your points.
