About function to evaluation

Hello Dear all:
My questions are as follows:
First I definite a function is f[x_,y_]:=2x+3y
Then I have a list is data={{1,2,0},{2,3,0},{4,1,0},{6,3,0},{1,3,0}}
For example{y,x,z}={1,2,0}    {y,x,z}={2,3,0}  {y,x,z}={4,1,0}
{y,x,z}={6,3,0} {y,x,z}={1,3,0}
I want to take the list data to the function to get the function
values.
Then express the form as follows at last

   x     y     f[x,y]
   2     1       7
   3     2      12
   1     4      14
   3     6      24
   3     1       9

PS: The z values is zero overall.
Please tell me how to get the function values in the list
Thank you very much
