How to graph the line y = 2 x ?

First, find the equation's two solution points and plot them on the graph.
First Point: For ${\displaystyle x=0}$
${\displaystyle y=2\cdot 0}$
${\displaystyle y=0}$ or ${\displaystyle (0,0)}$
First Point: For ${\displaystyle x=2}$
${\displaystyle y=2\cdot 2}$
${\displaystyle y=4}$ or ${\displaystyle (2,4)}$
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]}
