u can c that the difference between 2 consecutive y values is  a constant ... ( it' 2)
  then it's not a exponential graph...
   
and
  u must be able to  c that  the y value is always is twice the x value u've got
              x= 1 ---> y= 2
             x = 3 ----> y = 6
therefor the equation will be
            y= 2x

hope this will help ya !
