Respuesta :

Answer:

so ans is C.)yes;3.5x

Step-by-step explanation:

x | y

8 |28

16 |56

20|70

8*3.5=28

16*3.5=56

20*3.5=70

so ans is C.)yes;3.5x

The y varies directly with x and the proportional relation is y = 3.5x option (C) yes;3.5x is correct.

What is a proportional relationship?

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

We have data in the table:

x | y

8 |28

16 |56

20|70

y ∝ x

y = kx

Plug x = 8 y = 28

28 = 8k

k = 3.5

y = 3.5x

Thus, the y varies directly with x and the proportional relation is y = 3.5x option (C) yes;3.5x is correct.
