Question

The table below shows a proportional relationship. True or False?

Answer 1

According to the image, the table shows a relationship that is not proportional. First of all, you cannot multiply a number by 0 and get something other than 0. Anything multiplied by 0 is always 0.

Second, the rule is different for each row.

2x5=10

4x4=16

6x3.6=22

A proportional relationship must increase by the same amount, and this does not, which means it is not proportional.

Answer 2

Find common ratio

• 0+4(1)=4
• 2+4(2)=10
• 4+4(3)=16
• 6+4(4)=22

Yes they are proportional
