Question

• Explain why the graph representing Janets data does not model a proportional relationship

• Explain why Tarik’s data does not model a proportional relationship


PLEASEEE HELP ASAP!!

Answer 1

Janet's data does not form a straight line as the coordinate are not in proportion.

Tarik's data are in proportion becaus
`x \ and \ y` increases with a definite proportion.

Explanation:

Janet's data having coordinates
`(4,1) , (10,2) , (16,3)` and so on does not show a definite proportion.(the
`x \ and \ y)` values do not increases with a fixed rate).

However,

Tarik's data having
`(0,0) , (7,2) , (10.5,3) \ and \ (21,6)` are in definite proportion.

There is
`(3)/(2)` times increase in both
`'x' \ and \ 'y' \ from (7,2) \ to \ (10.5, 3)`.

Further from
`(10.5, 3) \ to \ (21,6)`

There is an increase of
`2 \ times` in both
`x \ and \ y`.

Thus those are the reason for Janet's model and Tarik's model.
