Answer:

yes

Step-by-step explanation:

The graph will be proportional if y/x is equal to a constant

3/1 =3

6/2 = 3

12/4 = 3

15/5=3

Since they are all equal to the same constant

The equation for the line is of the form

y = kx  or y = 3x

This is proportional

Answer:

Yes

Step-by-step explanation:

It's because it's all multiplied by 3. y=3x
