Question

when mirror on y axis what are the coordinates of a and b in the mirror​

Answer 1

Answer:

Explanation:

With respect to x axis:

In image of a point P(x, y) with respect to x axis, the change in only sign of ordinate of point so the image is Q(x, –y).

Q(x, –y).

P1 (–3, 1) & P2 (5, –2) are two points in II & IV quadrant respectively then their images are

Q1 (–3, –1) & Q2 (5, 2) in III & I quadrant respectively.

With respect to y axis:

In image of a point P(x, y) the change in sign of its abscissa so the image is Q(–x, y).
