which sequence of transformations will change figure pqrs to figure p′q′r′s′?

a coordinate grid is labeled from negative 5 to 0 to 5 on both x- and y-axes at increments of 1. figure pqrs has p at ordered pair negative 3, negative 2, q at negative 2, negative 3, r at negative 3, negative 4, s at negative 4, negative 4. figure p prime q prime r prime s prime has p prime at ordered pair 2, 3, q prime at 3, 2, r prime at 4, 3, s prime at 4, 4.
