lan's home is represented by the point \( ( 4,4 ) \) on the coordinate grid. Joe's home is represented by the point \( ( 10,6 ) \) on the coordinate grid. They want to meet at a diner is halfway between their houses (i.e., divides the line from lan's house to Joe's house in a \( 1 : 1 \) ratio). What are the coordinates of the diner?
\( ( 7,5 ) \)
\( ( 14,10 ) \)
\( ( 2,2 ) \)
\( ( 5,3 )\)
