On a number line, the directed line segment from [tex]\( Q \)[/tex] to [tex]\( S \)[/tex] has endpoints [tex]\( Q \)[/tex] at [tex]\(-2\)[/tex] and [tex]\( S \)[/tex] at [tex]\( 6 \)[/tex]. Point [tex]\( R \)[/tex] partitions the directed line segment from [tex]\( Q \)[/tex] to [tex]\( S \)[/tex] in a [tex]\( 3:2 \)[/tex] ratio. Rachel uses the section formula to find the location of point [tex]\( R \)[/tex] on the number line. Her work is shown below.
Let [tex]\( m = 3 \)[/tex], [tex]\( n = 2 \)[/tex], [tex]\( x_1 = -2 \)[/tex], and [tex]\( x_2 = 6 \)[/tex].
1. [tex]\( R = \frac{m x_2 + n x_1}{m + n} \)[/tex]
2. [tex]\( R = \frac{3(6) + 2(-2)}{3 + 2} \)[/tex]
What is the location of point [tex]\( R \)[/tex] on the number line?
A. [tex]\(\frac{14}{5}\)[/tex]
B. [tex]\(\frac{16}{5}\)[/tex]
C. [tex]\(\frac{18}{5}\)[/tex]
D. [tex]\(\frac{22}{5}\)[/tex]
