The answer choice which represents a proportional relationship as required to be identified in the task content is; y = 1/2x.
<h3>Which equation among the answer choices represents a proportional relationship?</h3>
It follows from the task content that the equation which represents a proportional relationship be identified.
On this note, it follows from observation that the equation; y = 1/2x represents a proportional relationship, more specifically the variables are inversely proportional and hence, we may conclude that the other equations are not entirely proportional.
This follows from the fact that the other equations are partly constant and partly varying.
