Answer 1

4. It cannot be a constant or unit rate relationship because the value of k = y/x vary across table values.

5. The relationship in Tuesday's table can be described by a constant unit rate.

What is a Constant Unit rate Relationship?

A constant unit rate relationship can be described as a relationship between two input and output variables, x and y, in such a way that, k = y/x. "k" is the constant of proportionality of the relationship or the unit rate between the two variables.

4. We have the following:

5/20 = 1/4

10/40 = 1/4

12/60 = 1/5

14/80 = 7/40

16/100 = 4/25

Thus, this cannot be a constant or unit rate relationship because the value of k = y/x vary across table values.

5. 4/20 = 1/5

8/40 = 1/5

12/60 = 1/5

16/80 = 1/5

20/100 = 1/5

Thus, the value of k is the same across all table values, therefore, the relationship in Tuesday's table can be described by a constant unit rate.
