The length can be found using the Pythagorean Theorem...
c^2=a^2+b^2 and in this case:
d^2=(dx^2)+(dy^2)
d^2=(3-7)^2+(12-9)^2
d^2=-4^2+3^2
d^2=16+9
d^2=25
d=5
So the length of AB=5 units.
Not sure how to put it into Matrix form but the answers would be.
11/2
-7
-19/2
and together that would be (11/2,-7.-19/2)
