Question

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

Answer 1

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(0)=2*0=0`

`f(1)=2*1=2`

Now you have to draw a line going through two calculated points: `(0,0)` and `(2,2)`

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