3) The only points on grid are (4, 4) and (6, 8). The latter point has scale factors of (6/4, 8/4) = (1.5, 2), corresponding to selection B.
4) Reflection across the y-axis uses the rule (x, y) → (-x, y), corresponding to selection B.
5) The question is ambiguous regarding whether the graph is of the original figure or its image. If we assume it is the original figure, the quadrant that is clockwise from quadrant II is quadrant I, corresponding to selection A.
