Question

Which equation represents the line shown on the graph?

Answer 1

Y=2x

Explanation:

You are multiplying 2 by the x axis

Answer 2

`y=2x`

Explanation:

The line passes through the origin,
`(0,0)` so its equation is of the form;

`y=mx`

The graph also passes through
`(2,4)`.

We substitute this point to obtain;

`4=2m`

We divide both sides by 2 to get;

`2=m`

We substitute the value of m into the equation to get;

`y=2x`

The correct answer is A
