See a solution process below:

First, find two points on the line line:

For $x = 0$ ;

$y = (1/2 * 0) + 2$

$y = 0 + 2$

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

For $x = 4$ (I picked $4$ because it is easy to multiply it by $1/2$ )

$y = (1/2 * 4) +2$

$y = 2 + 2$

$y = 4$ or $(4, 4)$

Next plot these two points on the graph:

graph{(x^2 + (y-2)^2-0.125)((x-4)^2+(y-4)^2-0.125)=0 [-20, 20, -10, 10]}

Now, draw a line through the two points:

graph{(y-(x/2)-2)(x^2 + (y-2)^2-0.125)((x-4)^2+(y-4)^2-0.125)=0 [-20, 20, -10, 10]}

How do you graph y= 1/2x + 2y= 1/2x + 2?
