Question

which term describes what is happening in the amount per trial vs. time graph? a constant amount is eaten. nothing is eaten. a changing amount is eaten. a negative amount is eaten.

Explanation:

In a graph of amount vs. time, if the graph is a straight - line passing through the origin (as in this case), it represents a proportional relationship. For a proportional relationship \(y = kx\) (where \(y\) is the amount consumed, \(x\) is time, and \(k\) is the constant of proportionality). The slope \(k=\frac{y}{x}\) is constant. This means that for each unit of time, the same (constant) amount is consumed.

Answer:

A. A constant amount is eaten.
