Final answer:
The vertical change between the points (2.5, 1) and (5, 2) is 1 unit, while the horizontal change is 2.5 units.
Step-by-step explanation:
To calculate the vertical and horizontal changes between the points (2.5, 1) and (5, 2), we need to find the differences in the x-values (horizontal change) and the y-values (vertical change).
The vertical change is the difference in the y-values of the two points, which is:
Vertical Change = y2 - y1 = 2 - 1 = 1
The vertical change between the points (2.5, 1) and (5, 2) is therefore 1 unit.
The horizontal change is the difference in the x-values of the two points, which is:
Horizontal Change = x2 - x1 = 5 - 2.5 = 2.5
The horizontal change between these points is 2.5 units.
