Answer:

y = 4x

Step-by-step explanation:

You just have to know the relationship of the perimeter with the side length.

If the side length is x, the perimeter would be P = 2x + 2x = 4x

so if the perimeter is y, then y = 4x

y = 4x is the equation of the line.  

One at a time, plug in the x values until you find one that gives the right y value.
