4.3B Notes - “Graphing Proportional Relationships” LESSON LAUNCH. Re-read the “KEY IDEA” on p. 160 (Direct Variation) and then answer all of the questions below. Two quantities (x and y) are in a proportional relationship when it can be represented by the equation _____________ This means the graph must pass through the _________________ (so it contains the point ( , ) and when x = 1, y = _____ (so it contains the point (1, ____ ). It also means there will be a ____________________________ rate of change. Tell whether x and y are in a proportional relationship. Explain your reasoning. If so, write an equation that represents the relationship.
