Find the constant and slope for the following direct variation equations. Then graph. 1. 2.
Identify which situations in numbers 1-9 below can be modeled by direct variation, inverse variation or neither; write the equation for the first six. 3. Fred earns $6.50 per hour. 4. Edwina earns $450 plus 7.5% commission on sales 5. A car travels 250 miles to Myrtle Beach; the faster it goes, the less time the trip takes. 6. For his flooring business, Joes nees to convert feet to yards. 7. The volume of the water in a swimming pool as it is filed at a rate of 200 gallons per minute. 8. If the area of a rectangle remains constant and the width decreases, then the length increases. 9. The volume of the water in a swimming pool as the water drains at a rate of 200 gallons per minute. 10. You purchase a new SUM; as age increases, the resale price decreases. Write a direct variation equation that relates to x and y. Assume the y varies directly as x. Then solve. 11. If y = -8 when x = -2, find x when y = 32. 12. If y = 45, when x = 15, find x when y = 15. 13. If y = -4 when x=2, find y when x = -6 14. If y = -9 when x = 3, find y when x = -5 15. The distance traveled varies directly with the time of travel. If the time traveled is 250 meters in 25 seconds, find the distance traveled in 60 seconds. Write an inverse variation equation that relates and y. Assume that y varies inversely as x. Then solve. 16. If y=4 when x = 8, find y when x=2. 17. If y=-7 when x=3, find y when x = -3 18. If y= -6 when x=-2, find y when x = 4 19. If y = -24 when x = -3, find x when y = -6 20. The cost per person to rent a mountain cabin is inversely proportional to the number of people who share the rent. If the cost is $36 per person when 5 people share, what is the cost per person when 8 people share?
THE QUIZ WILL ALSO INCLUDE 3 ITEMS WHERE YOU WILL IDENTIFY GRAPHS AS DIRECT, INVERSE OR NEITHER VARIATION.
