Since you have posted a question with multiple sub-parts, we will solve first three sub-parts for you. To get remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.

(A)

The given equation is $y=2x$.

Let's find two points on the graph of the given function and verify the options.

For x=1, $y=2\left(1\right)=2$.

So, the point is (1,2).

For x=2, $y=2\left(2\right)=4$.

So, the point is (2,4).

The two points (1,2)  and (2,4) lie on the graph of the line in option (5).

Therefore, the graph of $y=2x$ is option (5).
