Question

Dose y = 7.2x represent a proportional relationship, if so identify the constant of proportionality. If not, explain why not.

Answer 1

Yes it does

The constant of proportionality is 7.2

Explanation:

Here, we are to determine if the expression represents a proportionality relationship

From the question, we can see that this is so

If we placed x beneath y, we will have

y/x = 7.2

So therefore the ratio between the two is 7.2 and thus, the equation represents a proportional relationship
