See a solution process below:

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

First Point: For $x = 0$

$y = (2 * 0) + 4$

$y = 0 + 4$

$y = 4$ or $(0, 4)$

Second Point: For $x = -2$

$y = (2 * -2) + 4$

$y = -4 + 4$

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

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

graph{(x^2+(y-4)^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{(y-2x - 4)(x^2+(y-4)^2-0.035)((x+2)^2+y^2-0.035)=0 [-10, 10, -5, 5]}
