The equation that matches the graph of the proportional relationship is (b) y = 1/2x
How to determine the equation that matches the proportional relationship?
The complete question is added at the end of this solution
From the question, we have the graph that can be used in our computation:
On the graph, we have the following points
(x, y) = (0, 0) and (6, 3)
The equation of the proportional relationship is then calculated as
y = Y/X * x
Where
(X, Y) = (6, 3)
Substitute the known values in the above equation, so, we have the following representation
y = 3/6 * x
Evaluate
y = 1/2x
Hence, the equation is y = 1/2x
