Line segment RS has endpoints R (-2, 4) and S (-4, -1).
Line segment R"S" has endpoints R" (3, -3) and S" (5,2).
Name the transformation that maps line segment RS to line segment R"S".
O rotation of 90° counterclockwise about the origin, followed by a translation (x, y) = (x + 2 y + 1).
reflection over the line y = x, followed by a translation (x, y) + (x + 1, y + 1).
O rotation of 180° about the origin, followed by a translation (x, y) - (x + 1, y + 1).
o translation (x, y) → (x + 1, y + 1), followed by a rotation of 180°counterclockwise about the origin.
