Unfortunately, the description provided in your question doesn't contain enough information to determine the precise structure of the triangles or how they are combined to form the perimeter of the figure. However, I can explain how to approach the problem based on an assumption:
If we assume that each triangle shares a side with the next triangle (like when equilateral triangles are placed side by side), then each new triangle that is added to the figure will contribute to the perimeter by the length of one of its sides (assuming the triangles are all the same size).
For the sake of demonstration, let's assume each triangle is equilateral with a side length of 1 unit. Here's how to represent the relationship using a table, based on this assumption:
| Number of Triangles (x) | Perimeter (y) | Ordered Pair (x,y) |
|--------------------------|---------------|------------------------|
| 1 | 3 | (1, 3) |
| 2 | 5 | (2, 5) |
| 3 | 7 | (3, 7) |
The pattern suggests that for every new triangle added, the perimeter increases by 2 units, since you are adding only one new side to the perimeter (the other side is being shared with the adjacent triangle).
To represent this relationship in words:
"For each additional triangle, the perimeter increases by 2 units compared to the previous total perimeter."
The equation for this relationship can be represented as:
y = 2x + 1
This equation assumes that starting with one triangle (x = 1) gives a perimeter of 3 units, and every additional triangle adds 2 units to the perimeter, which is represented by the coefficient of x.
If you want to graph this relationship, the x-axis would represent the number of triangles, and the y-axis would represent the perimeter of the figure. The graph would display a straight line with a slope of 2 and a y-intercept at 1. Each point on the graph would represent an ordered pair (x,y) from the table.
Please note that this is a hypothetical example. To provide an accurate answer, the specific configuration of how the triangles are arranged to form the perimeter is needed. If the triangles do not share sides in the manner described, or the triangles are not equilateral, the actual relationship could be different.
