Question

write an expression to represent the change in vertical distance from (4, 2) to (x, y).

Explanation:

Step1: Identify vertical coordinates

The vertical coordinate of the starting point is $2$, and the vertical coordinate of the ending point is $y$.

Step2: Calculate vertical change

Subtract the starting vertical coordinate from the ending vertical coordinate.
$y - 2$

Answer:

$y - 2$
