- Direct Variation if there is some nonzero constant k such that k is called the constant of variation
- Slide 3
- Direct Variation Examples 1)
- Slide 4
- Suppose y varies directly as x and y = 28 when x = 5. Find the constant of variation: Write an equation of the form
- Slide 5
- Use the equation to find the value of y when x = 3. If you are not asked to find the constant of variation, you can use a proportion. Proportion Solve for y
- Slide 6
- Increases.
- Slide 7
- Inverse Variation As one value increases the other value decreases and vice versa.

- How do I determine whether it is Direct or Indirect Variation? How do I determine whether it is Direct or Indirect Variation?
- Slide 12
- Joint Variation One quantity varies directly as the product of two or more other quantities.
- Slide 13
- If y varies jointly as x and the cube of z and y = 16 when x = 4 and z =2, find y when x = - 8 and z = -3.
