## California Algebra 2 Answer Key Prentice Hall Section 2.3 Page 76 Direct Variation Problem 8

8. y is not directly variable to x

In this particular case there is no direct variation between y and x, meaning there is no constant of variation. y and x are related by some indirect means instead.

## California Algebra 2 Answer Key Prentice Hall Section 2.3 Page 76 Direct Variation

This section deals with direct variation, the answers for problems 1-5 are as follows:

1. The constant of variation is 2

y = 2x

2. The constant of variation is -3

y = -3x

3. y is not directly varying with the value of x

4. The constant of variation is 1/3

y = 1/3x

5. The constant of variation is 7

y = 7x

6. y is not directly variable to x

7. The constant of variation is -2

y = -2x
