The relationship is proportional
The relationship is non-proportional; the graph does not pass through the origin
The relationship is non-proportional; the graph would be an arc
The proportional relationship cannot be determined from the information provided. Unfortunately I'm unable to put photos of the graphs here so sorry for the inconvenience 😔
