0,-3
To work this out I would use the midpoint formula. (x1+x2)/2 , (y1+y2)/2
Therefore, (3+-9)/2 , (-4+0)/2
= -6/2. , -4/2
= -3 , -2
Now we know the half way point from AB, now we will use the same formula but instead of point B we will substitue the midpoint to work out the 1/4 point
Therefore, (3+-3)/2, (-4+-2)/2
=. 0/2, -6/2
=. 0, -3
Therfore the 1/4 way point from AB is 0,-3
