Which set of values could be from a direct proportion

First table

Step-by-step explanation:

We have to find the set of value which could be from a direct proportion.

We know that

Direct proportion :

When x is directly proportional to y

Where k=Proportionality constant

K remain constant when x and y are in direct proportion

From first table

When x and y are both varies then ratio of x and y remain constant.Hence, it is in direct proportion.

From second table

not ]define

It is not direct proportion because k does not remain constant.

From third table

It is not direct proportion because k does not remain constant.

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
