Direct & Inverse Variation Review

• direct variation
• inverse variation
• joint variation
• none of these

Which of the following represents indirect variation?

• y = kx
• y = k/x
• y = x/k
• y = mx + b

• y=4/21x

Is the given table a direct or inverse variation? What is the constant of variation?

• Direct, 12
• Inverse, 12
• Direct, 1/12
• Inverse, 1/12

What does the Direct Variation Equation look like?

• y= kx
