The distance from P to Q is Q-P = (14,-16)
So starting at P, add 1/4, 1/2, 3/4 of that.
If the three new points are A,B,C, then
A = P + 1/4 (Q-P) = (-4,7) + (7/2,-4) = (-1/2,3)
Now do B and C in like wise.

or
take the midpoint of the 2 given points to have 2 new segments,
then take the midpoints of the two new segments.

PQ=y2-y1/x2-x1 so PQ= -9-7/10--4" 5.7
