3. 6. Given A (4, 1) and B (-3, 0), find the point that divides the line segment AB two-thirds of the way from B to A.

4. 8. The map shows a straight highway between two towns
8. The map shows a straight highway between two towns. Highway planners want to build a rest stop somewhere between the two towns. He wants the rest stop to be 1/6 of the way from Ashton. At what coordinate point would the rest stop be located?

5. Consider the following problem:
Find the coordinates of point A along a directed line segment from C(3,2) to D(5,8) so that A partitions 𝐶𝐷 in a ratio of 1:1.
