On a number line the directed line segment from q to s has endpoints q at -14 and s at 2. point r partitions the directed line segment from q to s in a 3: 5 ratio. which expression correctly used the formula, to find the location of point r?

Step-by-step explanation:

The distance from Q to S is 2 - (-14), or 16.

We start at point Q.  Note how 3 and 5 add  up to 8, which allows us to write:

R = Q + (3/8)(16), or R = -14 + 6, or R = -8.

From R to S it is (5/8)(16), or 10 units.

The directed line segment is partitioned into segments of lengths 6 and 10, whose combined length is 16, as expected.
