Which points are reflections of each other across the y-axis? A coordinate plane. (–7, –3) and (7, –3) (–5, 4) and (5, –4) (1, –8) and (1, 8) (–3, 5) and (5, –3)
Rule for reflecting over the y-axis: P(x, y)--->P'(-x, y), so the answer is (–7, –3) and (7, –3). You might think the answer would be (–5, 4) and (5, –4) but it is not because (–5, 4) reflected across the y-axis is (5, -4).
