Question

X12.3Y111213Does the table show a direct proportionalrelationship? If so, what is the directproportion equation?

Answer 1

To be a proportional relationship all ratios must be equal:

y /x = 11/1 ≠12/2≠13/3

11/1 =11

12/2 =6

13/3=4.3333

11≠6≠4.3333

So, the table doesn't show a direct proportional relationship.
