1. Direct and Inverse Variation Continued… Tuesday, September 2, 2014

2. Where might I find this in the real world?

3. What is the proportion for Direct Variation?

4. What is the proportion for Inverse Variation?

5. Let’s Review

6. Remember the Direct and Inverse Variation equations? How can we use the equations to find the constant of variation (k)?

7. Examples: 1. y varies directly as x, and y = 4 when x = 2. 2. y varies inversly as x, and y = 2 when x = 6.

8. You try 1. If y varies directly as x, and y = -3 when x = 9. 2. If y varies inversely as x, and y = -1 when x = 2.

9. Can we solve word problems that have both types of variation? Let’s try it!

10. Practice makes perfect With your learning partner, on notebook paper, work the ODD problems from the Direct & Inverse Variation Worksheet.

11. Homework Complete the worksheet showing all your work on notebook paper.

12. Exit Ticket On half a sheet of notebook paper, in complete sentences, tell the similarities and differences of direct and inverse variation.
