Question

If P = (-2,7), Find:
Ry-axis (P)
([?], [])

Answer 1

(2, 7)

Explanation:

`R_{\text{y-axis}}(\text{P})` represents the reflection of a point P about the y-axis.

If a point (x, y) is reflected across y-axis, rule for the reflection is,

(x, y) → (-x, y)

If a point (-2, 7) follows the same rule, coordinates of the image point will be,

P(-2, 7) → P'(2, 7)

Therefore, answer is (2, 7).
