See a solution process below:

Explanation:

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

First Point: For x=0

(30)+3y=3

0+3y=3

3y=3

3y3=33

y=1 or (0,1)

Second Point: For y=0

3x+(30)=3

3x+0=3

3x=3

3x3=33

x=1 or (1,0)

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

graph{(x^2+(y-1)^2-0.025)((x-1)^2+y^2-0.025)=0 [-10, 10, -5, 5]}

Now, we can draw a straight line through the two points to graph the line:

graph{(3x + 3y - 3)(x^2+(y-1)^2-0.025)((x-1)^2+y^2-0.025)=0 [-10, 10, -5, 5]}
