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 * 0) + 2#

#y = 0 + 2#

#y = 2# or #(0, 2)#

Second Point:

For #x = 2#

#y = (3 * 2) + 2#

#y = 6 + 2#

#y = 8# or #(2, 8)#

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

graph{(x^2+(y-2)^2-0.075)((x-2)^2+(y-8)^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-3x-2)(x^2+(y-2)^2-0.075)((x-2)^2+(y-8)^2-0.075)=0 [-20, 20, -10, 10]}
