Hours | Miles

-----------------
1/4 | 1
1/2 | 2
3/4 | 3
1 | 4

At what ratio does the constant proportionality appear?

The constant proportionality appears at the ratio 1/4. This is because the number of miles is always equal to four times the number of hours.

How would you right 1/4 in (X, Y)?

To represent 1/4 in (X, Y) notation, you can write it as (1, 4). The X-value represents the number of hours and the Y-value represents the number of miles. In this case, 1/4 is represented as (1, 4) in (X, Y) notation, indicating 1 hour and 4 miles.

Answers for my original question:

(1, 4)
(1, 1/4)
(4, 1)
(1/4, 1)

Apologies for any confusion. The correct answer for your original question is (1/4, 1). This indicates that for every 1/4 of an hour, there is 1 mile.
