If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate. For each point (x, y) on the graph, ž is equal to k, where k is the unit rate. The point (1, k) is a point on the graph.
Hope this helps...
Answer:

Step-by-step explanation:
Given


Required
Determine the equation (y)
Let the steady rate be represented with r.
So, the equation (y) can be determined using:



N/8+4=28.
This is how you write out this equation.

Since all 4 triangles are equal, then the dimension of 1 triangle is:


The hypotenuse (x) of the triangle blue trim is represented by the blue trim
So:

This gives
