1. Section 5.1.1 Direct and Inverse Variation

2. Lesson Objective: Students will: Formally define and apply inverse and direct variation.

4. 1: 6.65 = 1000k p(120,000) = 0.00665($120,000) p(120,000) = $798 p(B) = 0.00665B

7. 2:

9. 5-3: Suppose y varies directly with the square of x. a: Express this relationship generally using k as the constant of variation.

10. 5-3: b: Solve for the specific solution (find the value of k and use it to write the equation of variation) if y = 3 when x = 2.

11. 5-3: c: Use the equation from part (b) to find y when x = -3.
