Re: Point

The distance between the X coordinates is 7-1=6.   2/3's of that is 4.   Your new X coordinate is 1+4=5.
The distance between the Y coordinates is 6-3=3.   2/3's of that is 2.   Your new Y coordinate is 3+2=5.
So the answer is (5,5).

Re: Point

Or, depending on how you interpret the question, it could also be (3,4).


Why did the vector cross the road?
It wanted to be normal.
