Answer:
[tex]y=2x[/tex]
Step-by-step explanation:
The line passes through the origin, [tex](0,0)[/tex] so its equation is of the form;
[tex]y=mx[/tex]
The graph also passes through [tex](2,4)[/tex].
We substitute this point to obtain;
[tex]4=2m[/tex]
We divide both sides by 2 to get;
[tex]2=m[/tex]
We substitute the value of m into the equation to get;
[tex]y=2x[/tex]
The correct answer is A
