Question

Determining If a Relationship is Proportional

Answer 1

Answer:

The table represents a proportional relationship

Step-by-step explanation:

Given

x ------ y

1 ------- 15

2 --------30

4 ---------60

5 -------- 75

Required

Determine if the table shows a proportional relationship

To check this, we make use of the following formula;

Where k is the proportionality constant

When x = 1, y = 15

When x = 2, y = 30

When x = 4, y = 60

When x = 5, y = 75

Since the value of k for all values of x and y is the same; i.e. 15

Then, the table represents a proportional relationship
