Answer:

  (-4, -7)

Step-by-step explanation:

You seem to want P on AB such that ...

  AP/PB = 6/1

  AP = 6PB . . . . . . . . multiply by PB

  P -A = 6(B -P) . . . . . show segment lengths as differences of point values

  7P = 6B +A . . . . . . . rearrange

  P = (6B +A)/7

We assume you want the directed segment AB such that A = (-10, -1) and B = (-3, -8). Then the point that does your partitioning is ...

  P = (6(-3, -8) +(-10, -1))/7 = (-28, -49)/7

  P = (-4, -7) . . . . the point that partitions the segment 6:1
