7 Notes and examples Determine whether the table represents an inverse or a direct variation. Explain.

8 Notes and examples Determine whether –2xy = 20 represents an inverse or a direct variation. Explain. Determine whether x = 0.5y represents an inverse or a direct variation. Explain.

9 Notes and examples Determine whether the table represents an inverse or a direct variation. Determine whether the table represents an inverse or a direct variation

10 Notes and examples Determine whether 2x = 4y represents an inverse or a direct variation. Determine whether represents an inverse or a direct variation. Assume that y varies inversely as x. If y = 5 when x = 3, write an inverse variation equation that relates x and y. Assume that y varies inversely as x. If y = –3 when x = 8, determine a correct inverse variation equation that relates x and y.

11 Notes and examples If y varies inversely as x and y = 6 when x = 40, find x when y = 30. Assume that y varies inversely as x. If y = 5 when x = 12, find x when y = 15.

12 Notes and examples PHYSICAL SCIENCE When two people are balanced on a seesaw, their distances from the center of the seesaw are inversely proportional to their weights. How far should a 105-pound person sit from the center of the seesaw to balance a 63-pound person sitting 3.5 feet from the center? PHYSICAL SCIENCE When two objects are balanced on a lever, their distances from the fulcrum are inversely proportional to their weights. How far should a 2-kilogram weight be from the fulcrum if a 6-kilogram weight is 3.2 meters from the fulcrum?

13 Notes and examples Graph an inverse variation in which y = 1 when x = 4. Graph an inverse variation in which y = 8 when x = 3.
