Final answer:
To describe the translation from point P to point P' using arrow notation, subtract the x and y coordinates of P from the x and y coordinates of P' respectively. The result is the arrow notation for the translation.
Step-by-step explanation:
In this problem, we are given the coordinates of point P as (8, -5) and the coordinates of point P' as (15, -6). To describe the translation from point P to point P' using arrow notation, we need to find the horizontal and vertical differences between the two points.
First, we subtract the x-coordinate of point P from the x-coordinate of point P' to find the horizontal difference: 15 - 8 = 7. Since the result is positive, the translation moves to the right.
Next, we subtract the y-coordinate of point P from the y-coordinate of point P' to find the vertical difference: -6 - (-5) = -1. Since the result is negative, the translation moves downward. Therefore, the arrow notation for the translation from point P to point P' is (7, -1).
