See a solution process below:

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

First Point: For $x = 0$

$y = 0 + 1$

$y = 1$ or $(0, 1)$

Second Point: For $x = 2$

$y = 2 + 1$

$y = 3$ or $(2, 3)$

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

graph{(x^2+(y-1)^2-0.035)((x-2)^2+(y-3)^2-0.035)=0 [-10, 10, -5, 5]}

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

graph{(y-x-1)(x^2+(y-1)^2-0.035)((x-2)^2+(y-3)^2-0.035)=0 [-10, 10, -5, 5]}
