Answer: D
Step-by-step explanation:
Plug in the ratio into the formula, so 2/2+3=2/5
Eliminate the first 2 options
Find the difference between x2 and x1
Find x2 and x1 by using the x-coordinates of the given points
I will use x1 as point a's x-value
x1=-3
x2=2
Altogether, you'll derive:

This matches D.
C won't work because although C and D will work with x1 and x2, C doesn't split it into a 2:3 ratio.
