See a solution process below:

Explanation:

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

First Point: For x=0

y=(230)+4

y=0+4

y=4 or (0,4)

Second Point: For x=3

y=(233)+4

y=2+4

y=2 or (3,2)

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

graph{(x^2+(y-4)^2-0.04)((x-3)^2+(y-2)^2-0.04)=0 [-10, 10, -5, 5]}

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

graph{(y + (2/3)x-4)(x^2+(y-4)^2-0.04)((x-3)^2+(y-2)^2-0.04)=0 [-10, 10, -5, 5]}
