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).

A linearized model would be the best in this case, since R \simeq 1 .

Step-by-step explanation:

Since, R-value or the correlation coefficient is 0.977 or very close to 1, so

linearized model will be best suitable as least square regression model.

Since,

when R = 1

the points will accurately fall over a straight line having equation of the form

ax + by + c = 0 where a, b, c are fixed but otherwise arbitrary constants.
