How to graph the line $y=2x$?

First, find the equation's two solution points and plot them on the graph.
First Point: For $x=0$
$y=2\cdot 0$
$y=0$ or $\left(0,0\right)$
First Point: For $x=2$
$y=2\cdot 2$
$y=4$ or $\left(2,4\right)$
We can next plot the two points on the coordinate plane:
graph{(x^2+y^2-0.025)((x-2)^2+(y-4)^2-0.025)=0 [-10, 10, -5, 5]}
Now, we can draw a straight line through the two points to graph the line:
graph{(y - 2x)(x^2+y^2-0.025)((x-2)^2+(y-4)^2-0.025)=0 [-10, 10, -5, 5]}
