Find the equation of the line y=mx through the origin that describes the proportional relationship shown in the graph.

(6,2) (3,1)

First, calculate the slope from the two points given:

m = (1-0)/(3-0) = 1/3

Now that we have the slope, we can substitute it back into the equation y=mx:
y = (1/3)x

Therefore, the equation of the line that describes the proportional relationship shown in the graph is y = (1/3)x.
