Question

If P=(3,4), find:
R y-axis (P)
Please help!!

Answer 1

P' = (- 3, 4 )

Explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ), hence

P(3, 4 ) → P'(- 3, 4 )

Answer 2

(-3,4)

Explanation:

That means to reflect the point across the y-axis... If you draw (3,4) on the coordinate plane you should see (-3,4) is the reflection across the y-axis from that point.
