Question

The following table shows the height of a plant at different ages.
please answer

Answer 1

The answer to your question is no. The reason behind this is it is a case of direct proportion in which the value x/y remains constan. But as we look at the given figure, we can see that the height is not keeping pace with its age in weeks as, the value x/y is not constant here. Means, it is not in proportion.
