See a solution process below:

First, solve for two points which solve the equation and plot these points:

First Point: For $x = 0$

$y = (1/3 * 0) + 3$

$y = 0 + 3$

$y = 3$ or $(0, 3)$

Second Point: For $x = 3$

$y = (1/3 * 3) + 3$

$y = 1 + 3$

$y = 4$ or $(1, 4)$

We can next plot the two points on the coordinate plane:

graph{(x^2+(y-3)^2-0.025)((x-3)^2+(y-4)^2-0.025)=0 [-10, 10, -5, 5]}

Now, we can draw a straight line through the two points to graph the line:

graph{(y - (1/3)x - 3)(x^2+(y-3)^2-0.025)((x-3)^2+(y-4)^2-0.025)=0 [-10, 10, -5, 5]}
