See a solution process below:

Explanation:

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

First Point: For x=0

0y=4

y=4

1y=14

y=4 or (0,4)

Second Point: For y=0

x+0=4

x=4 or (4,0)

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

graph{(x^2+(y+4)^2-0.035)((x-4)^2+y^2-0.035)=0 [-10, 10, -7, 3]}

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

graph{(x - y - 4)(x^2+(y+4)^2-0.035)((x-4)^2+y^2-0.035)=0 [-10, 10, -7, 3]}
