A point T on a segment with endpoints D (1, 4) and F (7, 1) partitions the segment in a 3:1 ratio. Find T. You must show all work to receive credit.
The change in x is from 1 to 7 6 units
The change in y is from 4 to 1 -3 units
A RATIO of 3:1 means the line is divided into FOUR segments (3+1)
we want three of those segments from endpoint D (an alternative would be three segments from fpoint F...I assumed from point D)
6 units x 3/4 added to the x value of 1 = x=5.5
-3 units x 3/4 added to the y value of 4 = y = 1.75
