Tell whether x and y are in a proportional relationship. Explain your reasoning. If so, write an equation that represents the relationship. (Select all that apply.)

• no, the graph of the equation

  does not pass through the

  origin.

• yes, the graph

  is a line through

  the origin.

Create a proportional graph that goes through the origin and has a slope of 4.
