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 = 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]}
