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 uses the formula (startfraction m over m + n endfraction) (x 2 minus x 1) + x 1 to find the location of point r? (startfraction 3 over 3 + 5 endfraction) (2 minus (negative 14)) + (negative 14) (startfraction 3 over 3 + 5 endfraction) (negative 14 minus 2) + 2 (startfraction 3 over 3 + 5 endfraction) (2 minus 14) + 14 startfraction 3 over 3 + 5 endfraction (negative 14 minus 2) minus 2
