Answer: The equation that represents the graph is y=4x.

Step-by-step explanation: If you plug in just one coordinate in each equation, you will find that these are the following outcomes no matter which coordinate you pick(but I'm picking (2,8) for your view):

y=x   ,    8=2

y=x   ,    8=2

y=2x    ,     8=4

y=4x   ,   8=8(ONLY CORRECT STATEMENT)

Answer:

y= 4x
