1. Translations day 2
Today we are going to learn how to PARTITION a line segment into any ratio, ALGEBRAICALLY

2. VOCAB: DIRECTED Line segment

4. STEP 1
Add the 2 numbers in the ratio

5. Step 2
Find the Translation that maps point R onto point S.

6. STEP 3 Now take that translation and split apart the 2 #’s.
Multiply each of those numbers by the 1st # in the ratio over the sum of the 2#’s in the ratio

7. STEP 4
This gives you a NEW TRANSLATION RULE that we are going to use to find out the coordinates of point Q.
