Question

Can someone please help I can’t figure it out I’m so confused

Answer 1

Since y=x has the same coefficient (of 1), this equation has a 1:1 ratio (another word for "it has the proportionality of 1).

If it's wrong, I'm sorry... Khan Academy is a little annoying...

Answer 2

`y =(10)/(11)x \rightarrow (10)/(11)`

`y=(7)/(8)x \rightarrow (7)/(8)`

`y = (3)/(15) \rightarrow (1)/(5)`

`y = x \rightarrow 1`

From the information given above, D is the answer which has a constant proportionality equal to 1.
