Does the table show a proportional relationship?

• Yes because it will pass through the origin
• No because it does not have the same C.O.P.
• Yes because it has the same C.O.P.
• No, because 2 does not divide into 27 evenly

Does the equation show a proportional relationship?

• Yes there is no C.O.P.
• No because if your x=0 then your y=9 and the line would not pass through the origin
• Yes because you add 9 and that is consistant
• No because there is no C.O.P.
