Okay, so YZ = 3 cm.  You have XM correct. And YM = 0.5.

Now, you have the midpoint M at the correct spot.

Use Pythagorean's theorem o find the length of AB.  a² + b² = c²   a=6,  b=8.

6² = 36   8² = 64    36 + 64 = 100      AB = 10!

If AB = 10   then AM = 5    MB also = 5

If B is the midpoint of AC,  C would be 12 rows down from A, and 16 columns to the right. The last spot where the line intersects.

There are your answers!
