proportional relationship? If so, what is the constant of proportionality? What does it represent? Write an equation to represent the distance d, in meters, that the horse runs in t seconds. 6 The equation c 5 6.4w represents the cost c for w pounds of walnuts. Does a value of 2.5 for w make sense in this situation? Explain your reasoning. Graphing Proportional Relationships can be completed by using values from a table or from an equation that contains a Proportional Relationship. Proportional Relationships are relationships that contain ratios that have a Constant of Proportionality. The Constant of Proportionality is the multiplier that relates the variables together.
