# How do you graph linear equation y=2x?

See explanation.

#### Explanation:

To draw a grah of a linear function you need two points. This means you need to calculate the function value for 2 aruments:

for example:

$f \left(0\right) = 2 \cdot 0 = 0$

$f \left(1\right) = 2 \cdot 1 = 2$

Now you have to draw a line going through two calculated points: $\left(0 , 0\right)$ and $\left(2 , 2\right)$

graph{(y-2x)(x^2+y^2-0.03)((x-1)^2+(y-2)^2-0.03)=0 [-10, 10, -5, 5]}
