See a solution process below:

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

First Point: For $x = 0$

$y = 5 - (4 xx 0)$

$y = 5 - 0$

$y = 5$ or $(0, 5)$

First Point: For $x = 2$

$y = 5 - (4 xx 2)$

$y = 5 - 8$

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

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

graph{(x^2+(y-5)^2-0.05)((x-2)^2+(y+3)^2-0.05)=0 [-15, 15, -7.5, 7.5]}

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

graph{(y-5+4x)(x^2+(y-5)^2-0.05)((x-2)^2+(y+3)^2-0.05)=0 [-15, 15, -7.5, 7.5]}

How do you graph y = 5 -4xy = 5 -4x?
