See a solution process below:
Explanation:
To graph a linear equation first solve for two points which solve the equation and plot these points:
First Point: For
Second Point: For
We can next plot the two points on the coordinate plane:
graph{(x^2+y^2-0.04)((x-2)^2+(y+4)^2-0.045)=0 [-10, 10, -5, 5]}
Now, we can draw a straight line through the two points to graph the line:
graph{(y + 2x)(x^2+y^2-0.04)((x-2)^2+(y+4)^2-0.045)=0 [-10, 10, -5, 5]}
