Answer:

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 = 2 + (3 * 0)#

#y = 2 + 0#

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

Second Point: For #x = 1#

#y = 2 + (3 * 1)#

#y = 2 + 3#

#y = 5# or #(1, 5)#

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

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

graph{(y-2-3x)(x^2+(y-2)^2-0.075)((x-1)^2+(y-5)^2-0.075)=0 [-20, 20, -10, 10]}
