See a solution process below:

Explanation:

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

First Point: For #x = 0#

#y = -1/4 xx 0#

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

Second Point: For #x = 4#

#y = -1/4 xx 4#

#y = -4/4#

#y = -1# or #(4, -1)#

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

graph{(x^2+y^2-0.035)((x-4)^2+(y+1)^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 + (1/4)x)(x^2+y^2-0.035)((x-4)^2+(y+1)^2-0.035)=0 [-10, 10, -5, 5]}
