See a solution process below:
Explanation:
First, solve for two points which solve the equation and plot these points:
First Point:
For
Second Point:
For
We can next graph the two points on the coordinate plane:
graph{(x^2+(y+4)^2-0.075)((x+1)^2+(y-5)^2-0.075)=0 [-20, 20, -10, 10]}
Now, we can draw a straight line through the two points to graph the equation:
graph{(y+9x+4)(x^2+(y+4)^2-0.075)((x+1)^2+(y-5)^2-0.075)=0 [-20, 20, -10, 10]}
