See a solution process below:

Explanation:

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

First Point: For x = 0x=0

y = 0 - 2y=02

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

Second Point: For x = 2x=2

y = 2 - 2y=22

y = 0y=0 or (2, 0)(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]}
