On a coordinate plane, 2 triangles are shown. the first triangle has points a (negative 2, 1), c (negative 4, 1), and b (negative 3, 4). the second triangle has points a prime (1, negative 2), b prime (4, negative 3), and c prime (1, negative 4). what is the rule for the reflection? ry=x(x, y) → (–y, –x) ry=–x(x, y) → (–y, –x) ry=x(x, y) → (y, x) ry=–x(x, y) → (y, x)
