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 - 2#

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

Second Point: For #x = 2#

#y = 2 - 2#

#y = 0# or #(2, 0)#

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

graph{(x^2+(y+2)^2-0.025)((x-2)^2+y^2-0.025)=0 [-10, 10, -5, 5]}

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

graph{(y-x+2)(x^2+(y+2)^2-0.025)((x-2)^2+y^2-0.025)=0 [-10, 10, -5, 5]}
