Answer:

B(-3, -3)

Explanation:

If a point O(x, y) divides line segment XY in the ratio of n:m and the endpoints of the segment are
X(x_1,y_1)\ and\ Y(x_2,y_2), the coordinates of O is:


x=(n)/(n+m)(x_2-x_1)+x_1 \\\\y=(n)/(n+m)(y_2-y_1)+y_1

Given that A(6, -6) and C(-6, 2). Pont B is on AC such that:

AB = (3/4)AC

AB/AC = 3/4

Therefore point B divides the line AC in the ratio of 3:1. Let point B be at (x, y), therefore:


x=(3)/(3+1)(-6-6)+6=(3)/(4)(-12)+6=-9+6=-3\\ \\y=x=(3)/(3+1)(-2-(-6))-6=(3)/(4)(4)-6=3-6=-3

Therefore the location of B is at (-3, -3)
