Answer:
M = 1 and M = -7.5
Step-by-step explanation:
The distance between A and B is 6 - (-1.5) = 7.5
Point 1: M is between AB. Since AM:MB = 1:2 then AM:AB = 1:(1+2) = 1:3
that means AM = 7.5 / 3 = 2.5
So M is at -1.5 + 2.5 = 1
Point 2: A is between MB. Since AM:MB = 1:2 then AM:AB = 1:(2-1) = 1
That means AM = AB = 6
So M is at -1.5 - 6 = -7.5
