The solution is

#### Explanation:

Start by plotting

graph{1/3x [-10, 10, -5, 5]}

This is a straight line passing through the origin.

Then on the same graph, plot

graph{(y-1/3x)(y-1/3x+2)=0 [-10, 10, -5, 5]}

The graph are parallel, therefore, no solutions

We could have reached the same conclusions, as the gradients of the

Gradient is
