determine whether the table represents a proportional relationship. if a proportional relationship exists, what is the constant ratio of y/x?

a) yes; −2/3

b) yes; −5/3

c) yes; −2/5

d) the table does not represent a proportional relationship.

Option A : yes;

Explanation:

The table represents a proportional relationship because the x-values increases at a constant rate of 3 units and y-values increases at a constant rate of 2 units.

Since, the table represents a proportional relationship, the constant ratio is given by

From the table, let us substitute the values for x and y

For and , the constant ratio is

Similarly, for and , the constant ratio is

For and , the constant ratio is

For and , the constant ratio is

Thus, the constant ratio is
