Answer:

y=5x

Step-by-step explanation:

A proportional relation is of the form [tex]y=kx[/tex]

To find k, we put any ordered pair from the table and solve for k.

From the table when x=1, k=5

This implies that:

[tex]5=k(1)[/tex]

We simplify to get;

[tex]k=5[/tex]

We put this back into the equation to get:

[tex]y=5x[/tex]
