The problem in the image discusses a proportional relationship between the side length $x$ of a regular pentagon and its perimeter $y$. Specifically, Ezra finds that the perimeter is always 5 times the side length. This gives the equation:

$y = 5x$

Here, $x$ represents the side length in inches, and $y$ represents the perimeter in inches. To graph this proportional relationship, you will need two points where $y = 5x$. Let's choose two points:

1. When $x = 0$, $y = 5(0) = 0$, so the point is $(0, 0)$.
2. When $x = 2$, $y = 5(2) = 10$, so the point is $(2, 10)$.

Now, you can draw a straight line passing through these two points $(0, 0)$ and $(2, 10)$ to represent the relationship $y = 5x$.

Do you want further explanation or more details about graphing or proportional relationships?

Here are five related questions to consider:

1. What would the perimeter be for a pentagon with a side length of 4 inches?
2. How does the graph of this relationship compare to the graph of $y = 2x$?
3. If the side length is doubled, how does that affect the perimeter?
4. What other polygons have a perimeter that is proportional to their side length?
5. How would the graph change if the pentagon had a different ratio between the perimeter and side length?

Tip: In proportional relationships like this, the graph is always a straight line that passes through the origin.
