See a solution process below:

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

First Point: For $x = 0$

$0 - y = 2$

$-y = 2$

$color(red)(-1) xx -y = color(red)(-1) xx 2$

$y = -2$ or $(0, -2)$

Second Point: For $y = 0$

$x - 0 = 2$

$x = 2$ 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]}
