See a solution process below:

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

First Point: For #x = 0#

#y = 3 - (4 * 0)#

#y = 3 - 0#

#y = 3# or #(0, 3)#

First Point: For #x = 2#

#y = 3 - (4 * 2)#

#y = 3 - 8#

#y = -5# or #(2, -5)#

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

graph{(x^2+(y-3)^2-0.075)((x-2)^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 line:

graph{(y-3+4x)(x^2+(y-3)^2-0.075)((x-2)^2+(y+5)^2-0.075)=0 [-20, 20, -10, 10]}
