a. The constant of proportionality is 30. - Incorrect. It seems like you made a typo and selected the correct answer within your response.
b. Write an equation that represents this graph. y = x + 15 - Correct.
c. This is a proportional relationship because the y-intercept is (2,30) - Incorrect. Proportional relationships occur when the ratio between y and x is constant. In this case, the y-intercept does not provide enough information to determine if it is a proportional relationship.
