The distance form A to M will be added to the point M to find B

 

x coordinate    from A to M  is  3 to 5    two units....add two x untis to M     5 + 2 = 7   this is the x coordinate of B

y coordintat     from A to M  is  8 to 4    - 4 untis    add - 4 units to M          4 -4 = 0    this is th y component  of B
