Final answer:
To identify the ratio and scale factor, we need to understand how point P partitions the directed line segment ZY. The ratio of ZP to ZY represents the scale factor.
Step-by-step explanation:
In order to identify the ratio and scale factor, we need to understand how point P partitions the directed line segment ZY. Point P will partition the segment into two parts: ZP and ZY. The ratio of ZP to ZY represents the scale factor. For example, if ZP is 3 units and ZY is 7 units, the ratio is 3:7. The scale factor in this case would be 3/7.
