Lines 10: Direct Variation

In this video, we are going to learn how to interpret and solve direct variation problems
  • We define direct variation and show it graphically
  • We give examples of word problems and science problems that are direct variation
  • We show how to determine whether a set of data is an example of direct variation or not
  • We list the steps and go through examples where we set up the direct variation equation, solve for k, then solve for one of the other variables using a given number
