Only the first graph with equation,

y = 11.5x

shows a proportional relationship between x and y.

Step-by-step explanation:

Only the first graph with equation,

y = 11.5x

shows a proportional relationship between x and y.

We know that y is proportional to x , written as,

y ∝ x

only when, y = [tex]k \times x[/tex]  where k ≠ 0

Answer:

The first graph

Step-by-step explanation:

Every other graph's equation is y=mx+b,and the +b part makes it non-proportional.
