Question

Which graph represents the same relation as the rule y = 2x, for all real numbers x?

Answer 1

first graph option A

Explanation:

Rule is y= 2x

Lets make a table to find out some point for graphing

Plug in some values for x and find out y

x y= 2x

-2 y=2(-2) = -4

0 y= 2(0)=0

2 y = 2(2)= 4

So the coordinates for graphing are (-2,-4) , (0,0) and (2,4)

The first graph has all the same coordinates .

So first graph represents the same relation

Answer 2

The answer is the first graph (A)
