Question

Which graph and equation shows a proportional relationship between x and y?

Answer 1

Answer:

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 = $k \times x$  where k ≠ 0

Answer 2

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.
