Answer:(0,2)
Step-by-step explanation:
Take origin (0,0) as point A and when you move one block east to point B then coordinates becomes (1,0)
Now you move 4 blocks north to point C then the coordinates of point C becomes (4,1)
Similarly, You move 1 block west to point D such that its co-ordinates becomes (0,4)
Finally you move from D to E, 2 blocks south such that point E becomes (0,2)
So, E is the friend's house and its coordinates are (0,2)
It can be diagramatically be represented by figure given below
