The equation which represents the lower unit rate of these two relationships is y = 2x/11.
<h3>How to determine the equation?</h3>
In order to determine the equation which represents the lower unit rate of these two relationships, we would find the slope of the given points.
Mathematically, the slope of a straight line can be calculated by using this formula;

Substituting the given parameters into the formula, we have;

Slope = 2/11.
From the standard equation, we have:
y = mx + c
y = 2x/11 + 0
y = 2x/11.
