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=2

y=2

1×y=1×2

y=2 or (0,2)

Second Point: For y=0

x0=2

x=2 or (2,0)

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

graph{(x^2+(y+2)^2-0.035)((x-2)^2+y^2-0.035)=0 [-10, 10, -5, 5]}

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

graph{(x-y-2)(x^2+(y+2)^2-0.035)((x-2)^2+y^2-0.035)=0 [-10, 10, -5, 5]}
