See a solution process below:

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

First Point: For $x = 0$ $x = 0$

$y = (\frac{1}{2} \cdot 0) + 2$ $y = (1/2 * 0) + 2$

$y = 0 + 2$ $y = 0 + 2$

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

Second Point: For $x = 2$ $x = 2$

$y = (\frac{1}{2} \cdot 2) + 2$ $y = (1/2 * 2) + 2$

$y = 1 + 2$ $y = 1 + 2$

$y = 3$ $y = 3$ or $(2, 3)$ $(2, 3)$

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

graph{(x^2+(y-2)^2-0.035)((x-2)^2+(y-3)^2-0.035)=0 [-10, 10, -5, 5]}

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

graph{(x^2+(y-2)^2-0.035)((x-2)^2+(y-3)^2-0.035)(y - (1/2x) - 2)=0 [-10, 10, -5, 5]}

How do you graph y=12x+2y= 1/2x + 2?
