Does anyone know what graph to choose?

The correct answer is:  "Graph 1" ;  that is, the "first graph to the left" .

             →  {among the two graphs provided as answer choices.}.

Note:

 The line drawn on the graph shown on the "first graph" — (that is, the graph shown to the far left, among the two graphs provided as answer choices) — reflect the linear equation given:
 
  " y = 6x " ;

and the line shown on the "first graph shown to the left" consists of the coordinates reflected on the table given:

" (0, 0) ,  (1, 6), (2, 12), (3, 18) " .

Note that the "second graph, to the far right, is incorrect;  the line provided in the "second graph" shows that:

when "x = 4" , "y = 20" .

This is incorrect; since:  

Given the equation:  

" y = 6x "  ;

→  y = 6(4) ;
 
→  y = 24 ;  NOT "20" ; so "Graph 2"  is incorrect.

The correct answer is:  "Graph 1" ;  that is, the "first graph to the left" .
