  1. What is an Inverse Variation?
  2. How to solve inverse variation problems?
  1. Identifying Indirect Variation Equations
    Classify the following variations. (Direct or Indirect).
    1. b=8ab = -8a
    2. m=n5m = \frac{n}{5}
    3. p=2qp = \frac{-2}{q}
    4. s=17×ts = \frac{1}{7} \times t
  2. Identifying Indirect Variation Graphs
    1. graph 2A
    2. graph 2B
  3. Evaluating Indirect Variations
    Find the missing variable.
    1. y y varies inversely with xx. If y=22y=22 when x=17x=-17, find yy when x=11x=11.
    2. y y varies inversely with xx. If y=30y=30 when x=18x=18, find xx when y=5y=5.
  4. Word Problem: Application of Indirect Variations
    The time it takes to fly from Canada to China varies inversely as the speed of the plane. If the journey takes 13 hours at 950 km/h, how long would it take at 650 km/h?
