SUMMARY
The relation R defined on the integers by xRy if x² = y² results in distinct equivalence classes represented as [n] = {-n, n} for each integer n. This indicates that each integer n corresponds to a unique equivalence class containing both n and -n. There are infinitely many equivalence classes, denoted as [1], [2], [3], and so forth, confirming the infinite nature of this relation on the set of integers.
