•explain why the graph representing janets data does not model a proportional relationship

• explain why tarik’s data does not model a proportional relationship

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

Tarik's data are in proportion becaus increases with a definite proportion.

Step-by-step explanation:

Janet's data having coordinates and so on does not show a  definite proportion.(the values do not increases with a fixed rate).

However,

Tarik's data having are in definite proportion.

There is times increase in both .

Further from

There is an increase of in both .

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

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1
