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 = (3 * 0) + 5

y = 0 + 5

y = 5 or (0, 5)

Second Point: For x = 1

y = (3 * 1) + 5

y = 3 + 5

y = 8 or (1, 8)

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

graph{(x^2+(y-5)^2-0.1)((x-1)^2+(y-8)^2-0.1)=0 [-20, 20, -10, 10]}

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

graph{(y-3x-5)(x^2+(y-5)^2-0.1)((x-1)^2+(y-8)^2-0.1)=0 [-20, 20, -10, 10]}
