Question

Each table represents a proportional relationship. For each, find theconstant of proportionality, k, and write an equation that represents therelationship. Write k as a simplified proper or improper fraction and use thegiven variables.

Answer 1

**For the first table:

*We determine the value of k, as follows:

`30=k(18)\Rightarrow k=(5)/(3)`

The equation that represents the table is:

`f=(5)/(3)d`

**For the second table:

*We determine the value of k, as follows:

`18=k(30)\Rightarrow k=(3)/(5)`

The equation that represents the table is:

`d=(3)/(5)f`
